jdk.time.OffsetTime — clojure-interop/java.time 1.0.5

A time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 10:15:30+01:00.

OffsetTime is an immutable date-time object that represents a time, often viewed as hour-minute-second-offset. This class stores all time fields, to a precision of nanoseconds, as well as a zone offset. For example, the value "13:45.30.123456789+02:00" can be stored in an OffsetTime.

This is a value-based class; use of identity-sensitive operations (including reference equality (==), identity hash code, or synchronization) on instances of OffsetTime may have unpredictable results and should be avoided. The equals method should be used for comparisons.

*-max clj

Static Constant.

The maximum supported OffsetTime, '23:59:59.999999999-18:00'. This is the time just before midnight at the end of the day in the minimum offset (larger negative offsets are later on the time-line). This combines LocalTime.MAX and ZoneOffset.MIN. This could be used by an application as a "far future" date.

type: java.time.OffsetTime

*-min clj

Static Constant.

The minimum supported OffsetTime, '00:00:00+18:00'. This is the time of midnight at the start of the day in the maximum offset (larger offsets are earlier on the time-line). This combines LocalTime.MIN and ZoneOffset.MAX. This could be used by an application as a "far past" date.

type: java.time.OffsetTime

*from clj

(*from temporal)

Obtains an instance of OffsetTime from a temporal object.

This obtains an offset time based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of OffsetTime.

The conversion extracts and combines the ZoneOffset and the LocalTime from the temporal object. Implementations are permitted to perform optimizations such as accessing those fields that are equivalent to the relevant objects.

This method matches the signature of the functional interface TemporalQuery allowing it to be used as a query via method reference, OffsetTime::from.

temporal - the temporal object to convert, not null - java.time.temporal.TemporalAccessor

returns: the offset time, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if unable to convert to an OffsetTime

*now clj

(*now)

(*now zone)

Obtains the current time from the system clock in the specified time-zone.

This will query the system clock to obtain the current time. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.

zone - the zone ID to use, not null - java.time.ZoneId

returns: the current time using the system clock, not null - java.time.OffsetTime

*of clj

(*of time offset)

(*of hour minute second nano-of-second offset)

Obtains an instance of OffsetTime from an hour, minute, second and nanosecond.

This creates an offset time with the four specified fields.

This method exists primarily for writing test cases. Non test-code will typically use other methods to create an offset time. LocalTime has two additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.

hour - the hour-of-day to represent, from 0 to 23 - int minute - the minute-of-hour to represent, from 0 to 59 - int second - the second-of-minute to represent, from 0 to 59 - int nano-of-second - the nano-of-second to represent, from 0 to 999,999,999 - int offset - the zone offset, not null - java.time.ZoneOffset

returns: the offset time, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if the value of any field is out of range

*of-instant clj

(*of-instant instant zone)

Obtains an instance of OffsetTime from an Instant and zone ID.

This creates an offset time with the same instant as that specified. Finding the offset from UTC/Greenwich is simple as there is only one valid offset for each instant.

The date component of the instant is dropped during the conversion. This means that the conversion can never fail due to the instant being out of the valid range of dates.

instant - the instant to create the time from, not null - java.time.Instant zone - the time-zone, which may be an offset, not null - java.time.ZoneId

returns: the offset time, not null - java.time.OffsetTime

*parse clj

(*parse text)

(*parse text formatter)

Obtains an instance of OffsetTime from a text string using a specific formatter.

The text is parsed using the formatter, returning a time.

text - the text to parse, not null - java.lang.CharSequence formatter - the formatter to use, not null - java.time.format.DateTimeFormatter

returns: the parsed offset time, not null - java.time.OffsetTime

throws: java.time.format.DateTimeParseException - if the text cannot be parsed

adjust-into clj

(adjust-into this temporal)

Adjusts the specified temporal object to have the same offset and time as this object.

This returns a temporal object of the same observable type as the input with the offset and time changed to be the same as this.

The adjustment is equivalent to using Temporal.with(TemporalField, long) twice, passing ChronoField.NANO_OF_DAY and ChronoField.OFFSET_SECONDS as the fields.

In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):

// these two lines are equivalent, but the second approach is recommended temporal = thisOffsetTime.adjustInto(temporal); temporal = temporal.with(thisOffsetTime);

This instance is immutable and unaffected by this method call.

temporal - the target object to be adjusted, not null - java.time.temporal.Temporal

returns: the adjusted object, not null - java.time.temporal.Temporal

throws: java.time.DateTimeException - if unable to make the adjustment

after? clj

(after? this other)

Checks if the instant of this OffsetTime is after that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo(java.time.OffsetTime) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

other - the other time to compare to, not null - java.time.OffsetTime

returns: true if this is after the instant of the specified time - boolean

at-date clj

(at-date this date)

Combines this time with a date to create an OffsetDateTime.

This returns an OffsetDateTime formed from this time and the specified date. All possible combinations of date and time are valid.

date - the date to combine with, not null - java.time.LocalDate

returns: the offset date-time formed from this time and the specified date, not null - java.time.OffsetDateTime

before? clj

(before? this other)

Checks if the instant of this OffsetTime is before that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo(java.time.OffsetTime) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

other - the other time to compare to, not null - java.time.OffsetTime

returns: true if this is before the instant of the specified time - boolean

compare-to clj

(compare-to this other)

Compares this OffsetTime to another time.

The comparison is based first on the UTC equivalent instant, then on the local time. It is "consistent with equals", as defined by Comparable.

For example, the following is the comparator order:

10:30+01:00 11:00+01:00 12:00+02:00 11:30+01:00 12:00+01:00 12:30+01:00

Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local time is compared to distinguish them. This step is needed to make the ordering consistent with equals().

To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

other - the other time to compare to, not null - java.time.OffsetTime

returns: the comparator value, negative if less, positive if greater - int

throws: java.lang.NullPointerException - if other is null

equal? clj

(equal? this other)

Checks if the instant of this OffsetTime is equal to that of the specified time applying both times to a common date.

This method differs from the comparison in compareTo(java.time.OffsetTime) and equals(java.lang.Object) in that it only compares the instant of the time. This is equivalent to converting both times to an instant using the same date and comparing the instants.

other - the other time to compare to, not null - java.time.OffsetTime

returns: true if this is equal to the instant of the specified time - boolean

equals clj

(equals this obj)

Checks if this time is equal to another time.

The comparison is based on the local-time and the offset. To compare for the same instant on the time-line, use isEqual(OffsetTime).

Only objects of type OffsetTime are compared, other types return false. To compare the underlying local time of two TemporalAccessor instances, use ChronoField.NANO_OF_DAY as a comparator.

obj - the object to check, null returns false - java.lang.Object

returns: true if this is equal to the other time - boolean

format clj

(format this formatter)

Formats this time using the specified formatter.

This time will be passed to the formatter to produce a string.

formatter - the formatter to use, not null - java.time.format.DateTimeFormatter

returns: the formatted time string, not null - java.lang.String

throws: java.time.DateTimeException - if an error occurs during printing

get clj

(get this field)

Gets the value of the specified field from this time as an int.

This queries this time for the value of the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time, except NANO_OF_DAY and MICRO_OF_DAY which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

field - the field to get, not null - java.time.temporal.TemporalField

returns: the value for the field - int

throws: java.time.DateTimeException - if a value for the field cannot be obtained or the value is outside the range of valid values for the field

get-hour clj

(get-hour this)

Gets the hour-of-day field.

returns: the hour-of-day, from 0 to 23 - int

get-long clj

(get-long this field)

Gets the value of the specified field from this time as a long.

This queries this time for the value of the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this time. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

field - the field to get, not null - java.time.temporal.TemporalField

returns: the value for the field - long

throws: java.time.DateTimeException - if a value for the field cannot be obtained

get-minute clj

(get-minute this)

This is the offset of the local time from UTC/Greenwich.

returns: the zone offset, not null - java.time.ZoneOffset

get-second clj

(get-second this)

Gets the second-of-minute field.

returns: the second-of-minute, from 0 to 59 - int

hash-code clj

(hash-code this)

A hash code for this time.

returns: a suitable hash code - int

minus clj

(minus this amount-to-subtract)

(minus this amount-to-subtract unit)

Returns a copy of this time with the specified amount subtracted.

This returns an OffsetTime, based on this one, with the amount in terms of the unit subtracted. If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.

This method is equivalent to plus(long, TemporalUnit) with the amount negated. See that method for a full description of how addition, and thus subtraction, works.

This instance is immutable and unaffected by this method call.

amount-to-subtract - the amount of the unit to subtract from the result, may be negative - long unit - the unit of the amount to subtract, not null - java.time.temporal.TemporalUnit

returns: an OffsetTime based on this time with the specified amount subtracted, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if the subtraction cannot be made

minus-hours clj

(minus-hours this hours)

Returns a copy of this OffsetTime with the specified number of hours subtracted.

This subtracts the specified number of hours from this time, returning a new time. The calculation wraps around midnight.

This instance is immutable and unaffected by this method call.

hours - the hours to subtract, may be negative - long

returns: an OffsetTime based on this time with the hours subtracted, not null - java.time.OffsetTime

minus-minutes clj

(minus-minutes this minutes)

This subtracts the specified number of seconds from this time, returning a new time. The calculation wraps around midnight.

This instance is immutable and unaffected by this method call.

seconds - the seconds to subtract, may be negative - long

returns: an OffsetTime based on this time with the seconds subtracted, not null - java.time.OffsetTime

plus clj

(plus this amount-to-add)

(plus this amount-to-add unit)

Returns a copy of this time with the specified amount added.

This returns an OffsetTime, based on this one, with the amount in terms of the unit added. If it is not possible to add the amount, because the unit is not supported or for some other reason, an exception is thrown.

If the field is a ChronoUnit then the addition is implemented by LocalTime.plus(long, TemporalUnit). The offset is not part of the calculation and will be unchanged in the result.

If the field is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.addTo(Temporal, long) passing this as the argument. In this case, the unit determines whether and how to perform the addition.

This instance is immutable and unaffected by this method call.

amount-to-add - the amount of the unit to add to the result, may be negative - long unit - the unit of the amount to add, not null - java.time.temporal.TemporalUnit

returns: an OffsetTime based on this time with the seconds added, not null - java.time.OffsetTime

query clj

(query this query)

Queries this time using the specified query.

This queries this time using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.

The result of this method is obtained by invoking the TemporalQuery.queryFrom(TemporalAccessor) method on the specified query passing this as the argument.

query - the query to invoke, not null - java.time.temporal.TemporalQuery

returns: the query result, null may be returned (defined by the query) - <R> R

throws: java.time.DateTimeException - if unable to query (defined by the query)

range clj

(range this field)

Gets the range of valid values for the specified field.

The range object expresses the minimum and maximum valid values for a field. This time is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.

field - the field to query the range for, not null - java.time.temporal.TemporalField

returns: the range of valid values for the field, not null - java.time.temporal.ValueRange

throws: java.time.DateTimeException - if the range for the field cannot be obtained

supported? clj

(supported? this field)

Checks if the specified field is supported.

This checks if this time can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

If the field is a ChronoField then the query is implemented here. The supported fields are:

NANO_OF_SECOND NANO_OF_DAY MICRO_OF_SECOND MICRO_OF_DAY MILLI_OF_SECOND MILLI_OF_DAY SECOND_OF_MINUTE SECOND_OF_DAY MINUTE_OF_HOUR MINUTE_OF_DAY HOUR_OF_AMPM CLOCK_HOUR_OF_AMPM HOUR_OF_DAY CLOCK_HOUR_OF_DAY AMPM_OF_DAY OFFSET_SECONDS

All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

field - the field to check, null returns false - java.time.temporal.TemporalField

returns: true if the field is supported on this time, false if not - boolean

to-local-time clj

(to-local-time this)

Gets the LocalTime part of this date-time.

This returns a LocalTime with the same hour, minute, second and nanosecond as this date-time.

returns: the time part of this date-time, not null - java.time.LocalTime

to-string clj

(to-string this)

Outputs this time as a String, such as 10:15:30+01:00.

The output will be one of the following ISO-8601 formats:

HH:mmXXXXX HH:mm:ssXXXXX HH:mm:ss.SSSXXXXX HH:mm:ss.SSSSSSXXXXX HH:mm:ss.SSSSSSSSSXXXXX

The format used will be the shortest that outputs the full value of the time where the omitted parts are implied to be zero.

returns: a string representation of this time, not null - java.lang.String

truncated-to clj

(truncated-to this unit)

Returns a copy of this OffsetTime with the time truncated.

Truncation returns a copy of the original time with fields smaller than the specified unit set to zero. For example, truncating with the minutes unit will set the second-of-minute and nano-of-second field to zero.

The unit must have a duration that divides into the length of a standard day without remainder. This includes all supplied time units on ChronoUnit and DAYS. Other units throw an exception.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

unit - the unit to truncate to, not null - java.time.temporal.TemporalUnit

returns: an OffsetTime based on this time with the time truncated, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if unable to truncate

until clj

(until this end-exclusive unit)

Calculates the amount of time until another time in terms of the specified unit.

This calculates the amount of time between two OffsetTime objects in terms of a single TemporalUnit. The start and end points are this and the specified time. The result will be negative if the end is before the start. For example, the amount in hours between two times can be calculated using startTime.until(endTime, HOURS).

The Temporal passed to this method is converted to a OffsetTime using from(TemporalAccessor). If the offset differs between the two times, then the specified end time is normalized to have the same offset as this time.

The calculation returns a whole number, representing the number of complete units between the two times. For example, the amount in hours between 11:30Z and 13:29Z will only be one hour as it is one minute short of two hours.

There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):

// these two lines are equivalent amount = start.until(end, MINUTES); amount = MINUTES.between(start, end); The choice should be made based on which makes the code more readable.

The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

This instance is immutable and unaffected by this method call.

end-exclusive - the end time, exclusive, which is converted to an OffsetTime, not null - java.time.temporal.Temporal unit - the unit to measure the amount in, not null - java.time.temporal.TemporalUnit

returns: the amount of time between this time and the end time - long

throws: java.time.DateTimeException - if the amount cannot be calculated, or the end temporal cannot be converted to an OffsetTime

with clj

(with this adjuster)

(with this field new-value)

Returns a copy of this time with the specified field set to a new value.

This returns an OffsetTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour, minute or second. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the adjustment is implemented here.

The OFFSET_SECONDS field will return a time with the specified offset. The local time is unaltered. If the new offset value is outside the valid range then a DateTimeException will be thrown.

The other supported fields will behave as per the matching method on LocalTime.with(TemporalField, long) LocalTime}. In this case, the offset is not part of the calculation and will be unchanged.

All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.

This instance is immutable and unaffected by this method call.

field - the field to set in the result, not null - java.time.temporal.TemporalField new-value - the new value of the field in the result - long

returns: an OffsetTime based on this with the specified field set, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if the field cannot be set

with-hour clj

(with-hour this hour)

Returns a copy of this OffsetTime with the hour-of-day altered.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

hour - the hour-of-day to set in the result, from 0 to 23 - int

throws: java.time.DateTimeException - if the hour value is invalid

with-minute clj

(with-minute this minute)

Returns a copy of this OffsetTime with the minute-of-hour altered.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

throws: java.time.DateTimeException - if the minute value is invalid

with-nano clj

(with-nano this nano-of-second)

Returns a copy of this OffsetTime with the nano-of-second altered.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

nano-of-second - the nano-of-second to set in the result, from 0 to 999,999,999 - int

returns: an OffsetTime based on this time with the requested nanosecond, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if the nanos value is invalid

with-offset-same-instant clj

(with-offset-same-instant this offset)

Returns a copy of this OffsetTime with the specified offset ensuring that the result is at the same instant on an implied day.

This method returns an object with the specified ZoneOffset and a LocalTime adjusted by the difference between the two offsets. This will result in the old and new objects representing the same instant on an implied day. This is useful for finding the local time in a different offset. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 11:30+03:00.

To change the offset without adjusting the local time use withOffsetSameLocal(java.time.ZoneOffset).

This instance is immutable and unaffected by this method call.

offset - the zone offset to change to, not null - java.time.ZoneOffset

returns: an OffsetTime based on this time with the requested offset, not null - java.time.OffsetTime

with-offset-same-local clj

(with-offset-same-local this offset)

Returns a copy of this OffsetTime with the specified offset ensuring that the result has the same local time.

This method returns an object with the same LocalTime and the specified ZoneOffset. No calculation is needed or performed. For example, if this time represents 10:30+02:00 and the offset specified is +03:00, then this method will return 10:30+03:00.

To take into account the difference between the offsets, and adjust the time fields, use withOffsetSameInstant(java.time.ZoneOffset).

This instance is immutable and unaffected by this method call.

offset - the zone offset to change to, not null - java.time.ZoneOffset

returns: an OffsetTime based on this time with the requested offset, not null - java.time.OffsetTime

with-second clj

(with-second this second)

Returns a copy of this OffsetTime with the second-of-minute altered.

The offset does not affect the calculation and will be the same in the result.

This instance is immutable and unaffected by this method call.

second - the second-of-minute to set in the result, from 0 to 59 - int

returns: an OffsetTime based on this time with the requested second, not null - java.time.OffsetTime

throws: java.time.DateTimeException - if the second value is invalid
