public final class OffsetTime extends Object implements Temporal, TemporalAdjuster, Comparable<OffsetTime>, Serializable
A time with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as10:15:30+01:00.OffsetTimeis 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 anOffsetTime.This is a value-based class; use of identity-sensitive operations (including reference equality (
==), identity hash code, or synchronization) on instances ofOffsetTimemay have unpredictable results and should be avoided. Theequalsmethod should be used for comparisons.- Implementation Requirements:
- This class is immutable and thread-safe.

MIN
public static final OffsetTime MIN
The minimum supportedOffsetTime, '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 combinesLocalTime.MINandZoneOffset.MAX. This could be used by an application as a "far past" date.
-
MAX
public static final OffsetTime MAX
The maximum supportedOffsetTime, '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 combinesLocalTime.MAXandZoneOffset.MIN. This could be used by an application as a "far future" date.

now
public static OffsetTime now()
Obtains the current time from the system clock in the default time-zone.This will query the
system clockin the default time-zone to obtain the current time. The offset will be calculated from the time-zone in the clock.Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
- Returns:
- the current time using the system clock and default time-zone, not null
-
now
public static OffsetTime now(ZoneId zone)
Obtains the current time from the system clock in the specified time-zone.This will query the
system clockto 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.
- Parameters:
zone- the zone ID to use, not null- Returns:
- the current time using the system clock, not null
-
now
public static OffsetTime now(Clock clock)
Obtains the current time from the specified clock.This will query the specified clock to obtain the current time. The offset will be calculated from the time-zone in the clock.
Using this method allows the use of an alternate clock for testing. The alternate clock may be introduced using
dependency injection.- Parameters:
clock- the clock to use, not null- Returns:
- the current time, not null
-
of
public static OffsetTime of(LocalTime time, ZoneOffset offset)
Obtains an instance ofOffsetTimefrom a local time and an offset.- Parameters:
time- the local time, not nulloffset- the zone offset, not null- Returns:
- the offset time, not null
-
of
public static OffsetTime of(int hour, int minute, int second, int nanoOfSecond, ZoneOffset offset)
Obtains an instance ofOffsetTimefrom 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.
LocalTimehas two additional convenience variants of the equivalent factory method taking fewer arguments. They are not provided here to reduce the footprint of the API.- Parameters:
hour- the hour-of-day to represent, from 0 to 23minute- the minute-of-hour to represent, from 0 to 59second- the second-of-minute to represent, from 0 to 59nanoOfSecond- the nano-of-second to represent, from 0 to 999,999,999offset- the zone offset, not null- Returns:
- the offset time, not null
- Throws:
DateTimeException- if the value of any field is out of range
-
ofInstant
public static OffsetTime ofInstant(Instant instant, ZoneId zone)
Obtains an instance ofOffsetTimefrom anInstantand 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.
- Parameters:
instant- the instant to create the time from, not nullzone- the time-zone, which may be an offset, not null- Returns:
- the offset time, not null
-
from
public static OffsetTime from(TemporalAccessor temporal)
Obtains an instance ofOffsetTimefrom a temporal object.This obtains an offset time based on the specified temporal. A
TemporalAccessorrepresents an arbitrary set of date and time information, which this factory converts to an instance ofOffsetTime.The conversion extracts and combines the
ZoneOffsetand theLocalTimefrom 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
TemporalQueryallowing it to be used as a query via method reference,OffsetTime::from.- Parameters:
temporal- the temporal object to convert, not null- Returns:
- the offset time, not null
- Throws:
DateTimeException- if unable to convert to anOffsetTime
-

Returns a copy of thisOffsetTimewith the specified number of seconds subtracted.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.
- Parameters:
seconds- the seconds to subtract, may be negative- Returns:
- an
OffsetTimebased on this time with the seconds subtracted, not null
-
minusNanos
public OffsetTime minusNanos(long nanos)
Returns a copy of thisOffsetTimewith the specified number of nanoseconds subtracted.This subtracts the specified number of nanoseconds from this time, returning a new time. The calculation wraps around midnight.
This instance is immutable and unaffected by this method call.
- Parameters:
nanos- the nanos to subtract, may be negative- Returns:
- an
OffsetTimebased on this time with the nanoseconds subtracted, not null
-
query
public <R> R query(TemporalQuery<R> query)
Queries this time using the specified query.This queries this time using the specified query strategy object. The
TemporalQueryobject 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 passingthisas the argument.- Specified by:
queryin interfaceTemporalAccessor- Type Parameters:
R- the type of the result- Parameters:
query- the query to invoke, not null- Returns:
- the query result, null may be returned (defined by the query)
- Throws:
DateTimeException- if unable to query (defined by the query)ArithmeticException- if numeric overflow occurs (defined by the query)
-
adjustInto
public Temporal adjustInto(Temporal 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, passingChronoField.NANO_OF_DAYandChronoField.OFFSET_SECONDSas 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.
- Specified by:
adjustIntoin interfaceTemporalAdjuster- Parameters:
temporal- the target object to be adjusted, not null- Returns:
- the adjusted object, not null
- Throws:
DateTimeException- if unable to make the adjustmentArithmeticException- if numeric overflow occurs
-
until
public long until(Temporal endExclusive, TemporalUnit unit)
Calculates the amount of time until another time in terms of the specified unit.This calculates the amount of time between two
OffsetTimeobjects in terms of a singleTemporalUnit. The start and end points arethisand 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 usingstartTime.until(endTime, HOURS).The
Temporalpassed to this method is converted to aOffsetTimeusingfrom(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 unitsNANOS,MICROS,MILLIS,SECONDS,MINUTES,HOURSandHALF_DAYSare supported. OtherChronoUnitvalues will throw an exception.If the unit is not a
ChronoUnit, then the result of this method is obtained by invokingTemporalUnit.between(Temporal, Temporal)passingthisas the first argument and the converted input temporal as the second argument.This instance is immutable and unaffected by this method call.
- Specified by:
untilin interfaceTemporal- Parameters:
endExclusive- the end time, exclusive, which is converted to anOffsetTime, not nullunit- the unit to measure the amount in, not null- Returns:
- the amount of time between this time and the end time
- Throws:
DateTimeException- if the amount cannot be calculated, or the end temporal cannot be converted to anOffsetTimeUnsupportedTemporalTypeException- if the unit is not supportedArithmeticException- if numeric overflow occurs
-
format
public String format(DateTimeFormatter formatter)
Formats this time using the specified formatter.This time will be passed to the formatter to produce a string.
- Parameters:
formatter- the formatter to use, not null- Returns:
- the formatted time string, not null
- Throws:
DateTimeException- if an error occurs during printing
-
atDate
public OffsetDateTime atDate(LocalDate date)
Combines this time with a date to create anOffsetDateTime.This returns an
OffsetDateTimeformed from this time and the specified date. All possible combinations of date and time are valid.- Parameters:
date- the date to combine with, not null- Returns:
- the offset date-time formed from this time and the specified date, not null
-
toEpochSecond
public long toEpochSecond(LocalDate date)
Converts thisOffsetTimeto the number of seconds since the epoch of 1970-01-01T00:00:00Z.This combines this offset time with the specified date to calculate the epoch-second value, which is the number of elapsed seconds from 1970-01-01T00:00:00Z. Instants on the time-line after the epoch are positive, earlier are negative.
- Parameters:
date- the localdate, not null- Returns:
- the number of seconds since the epoch of 1970-01-01T00:00:00Z, may be negative
- Since:
- 9
-
compareTo
public int compareTo(OffsetTime other)
Compares thisOffsetTimeto 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+01:0011:00+01:0012:00+02:0011:30+01:0012:00+01:0012:30+01:00
equals().To compare the underlying local time of two
TemporalAccessorinstances, useChronoField.NANO_OF_DAYas a comparator.- Specified by:
compareToin interfaceComparable<OffsetTime>- Parameters:
other- the other time to compare to, not null- Returns:
- the comparator value, negative if less, positive if greater
-
isAfter
public boolean isAfter(OffsetTime other)
Checks if the instant of thisOffsetTimeis 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.- Parameters:
other- the other time to compare to, not null- Returns:
- true if this is after the instant of the specified time
-
isBefore
public boolean isBefore(OffsetTime other)
Checks if the instant of thisOffsetTimeis 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.- Parameters:
other- the other time to compare to, not null- Returns:
- true if this is before the instant of the specified time
-
isEqual
public boolean isEqual(OffsetTime other)
Checks if the instant of thisOffsetTimeis 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)andequals(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.- Parameters:
other- the other time to compare to, not null- Returns:
- true if this is equal to the instant of the specified time
-
equals
public boolean equals(Object 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
OffsetTimeare compared, other types return false. To compare the underlying local time of twoTemporalAccessorinstances, useChronoField.NANO_OF_DAYas a comparator.- Overrides:
equalsin classObject- Parameters:
obj- the object to check, null returns false- Returns:
- true if this is equal to the other time
- See Also:
Object.hashCode()
