ZonedDateTime

Companion object ZonedDateTime

final class ZonedDateTime extends ChronoZonedDateTime[LocalDate] with Temporal with Serializable

A date-time with a time-zone in the ISO-8601 calendar system, such as 2007-12-03T10:15:30+01:00 Europe/Paris.

ZonedDateTime is an immutable representation of a date-time with a time-zone. This class stores all date and time fields, to a precision of nanoseconds, and a time-zone, with a zone offset used to handle ambiguous local date-times. For example, the value "2nd October 2007 at 13:45.30.123456789 +02:00 in the Europe/Paris time-zone" can be stored in a ZonedDateTime.

This class handles conversion from the local time-line of LocalDateTime to the instant time-line of Instant. The difference between the two time-lines is the offset from UTC/Greenwich, represented by a ZoneOffset.

Converting between the two time-lines involves calculating the offset using the rules accessed from the ZoneId. Obtaining the offset for an instant is simple, as there is exactly one valid offset for each instant. By contrast, obtaining the offset for a local date-time is not straightforward. There are three cases:

Normal, with one valid offset. For the vast majority of the year, the normal case applies, where there is a single valid offset for the local date-time.
Gap, with zero valid offsets. This is when clocks jump forward typically due to the spring daylight savings change from "winter" to "summer". In a gap there are local date-time values with no valid offset.
Overlap, with two valid offsets. This is when clocks are set back typically due to the autumn daylight savings change from "summer" to "winter". In an overlap there are local date-time values with two valid offsets.

Any method that converts directly or implicitly from a local date-time to an instant by obtaining the offset has the potential to be complicated.

For Gaps, the general strategy is that if the local date-time falls in the middle of a Gap, then the resulting zoned date-time will have a local date-time shifted forwards by the length of the Gap, resulting in a date-time in the later offset, typically "summer" time.

For Overlaps, the general strategy is that if the local date-time falls in the middle of an Overlap, then the previous offset will be retained. If there is no previous offset, or the previous offset is invalid, then the earlier offset is used, typically "summer" time.. Two additional methods, #withEarlierOffsetAtOverlap() and #withLaterOffsetAtOverlap(), help manage the case of an overlap.

Specification for implementors

A ZonedDateTime holds state equivalent to three separate objects, a LocalDateTime, a ZoneId and the resolved ZoneOffset. The offset and local date-time are used to define an instant when necessary. The zone ID is used to obtain the rules for how and when the offset changes. The offset cannot be freely set, as the zone controls which offsets are valid.

This class is immutable and thread-safe.

def minus(amountToSubtract: Long, unit: TemporalUnit): ZonedDateTime
Returns a copy of this date-time with the specified period subtracted.
Returns a copy of this date-time with the specified period subtracted.
This method returns a new date-time based on this date-time with the specified period subtracted. This can be used to subtract any period that is defined by a unit, for example to subtract years, months or days. The unit is responsible for the details of the calculation, including the resolution of any edge cases in the calculation.
The calculation for date and time units differ.
Date units operate on the local time-line. The period is first subtracted from the local date-time, then converted back to a zoned date-time using the zone ID. The conversion uses ZoneId, ZoneOffset) with the offset before the subtraction.
Time units operate on the instant time-line. The period is first subtracted from the local date-time, then converted back to a zoned date-time using the zone ID. The conversion uses ZoneOffset, ZoneId) with the offset before the subtraction.

Returns a copy of this ZonedDateTime with the specified period in hours subtracted.
Returns a copy of this ZonedDateTime with the specified period in hours subtracted.
This operates on the instant time-line, such that subtracting one hour will always be a duration of one hour earlier. This may cause the local date-time to change by an amount other than one hour. Note that this is a different approach to that used by days, months and years, thus subtracting one day is not the same as adding 24 hours.
For example, consider a time-zone where the spring DST cutover means that the local times 01:00 to 01:59 occur twice changing from offset +02:00 to +01:00.
- Subtracting one hour from 02:30+01:00 will result in 01:30+02:00
- Subtracting one hour from 01:30+01:00 will result in 01:30+02:00
- Subtracting one hour from 01:30+02:00 will result in 00:30+01:00

def truncatedTo(unit: TemporalUnit): ZonedDateTime
Returns a copy of this ZonedDateTime with the time truncated.
Returns a copy of this ZonedDateTime with the time truncated.
Truncation returns a copy of the original date-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.
This operates on the local time-line, truncating the underlying local date-time. This is then converted back to a ZonedDateTime, using the zone ID to obtain the offset.
When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise the earlier offset will be used. If in a gap, the local date-time will be adjusted forward by the length of the gap.

def until(endExclusive: Temporal, unit: TemporalUnit): Long
Calculates the period between this date-time and another date-time in terms of the specified unit.
Calculates the period between this date-time and another date-time in terms of the specified unit.
This calculates the period between two date-times in terms of a single unit. The start and end points are this and the specified date-time. The result will be negative if the end is before the start. For example, the period in days between two date-times can be calculated using startDateTime.until(endDateTime, DAYS).
The Temporal passed to this method must be a ZonedDateTime. If the time-zone differs between the two zoned date-times, the specified end date-time is normalized to have the same zone as this date-time.
The calculation returns a whole number, representing the number of complete units between the two date-times. For example, the period in months between 2012-06-15T00:00Z and 2012-08-14T23:59Z will only be one month as it is one minute short of two months.
This method operates in association with TemporalUnit#between. The result of this method is a long representing the amount of the specified unit. By contrast, the result of between is an object that can be used directly in addition/subtraction:
```
long period = start.until(end, MONTHS);   // this method
dateTime.plus(MONTHS.between(start, end));      // use in plus/minus
```
The calculation is implemented in this method for ChronoUnit. The units NANOS, MICROS, MILLIS, SECONDS, MINUTES, HOURS and HALF_DAYS, DAYS, WEEKS, MONTHS, YEARS, DECADES, CENTURIES, MILLENNIA and ERAS are supported. Other ChronoUnit values will throw an exception.
The calculation for date and time units differ.
Date units operate on the local time-line, using the local date-time. For example, the period from noon on day 1 to noon the following day in days will always be counted as exactly one day, irrespective of whether there was a daylight savings change or not.
Time units operate on the instant time-line. The calculation effectively converts both zoned date-times to instants and then calculates the period between the instants. For example, the period from noon on day 1 to noon the following day in hours may be 23, 24 or 25 hours (or some other amount) depending on whether there was a daylight savings change or not.
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 input temporal as the second argument.
This instance is immutable and unaffected by this method call.

def with(field: TemporalField, newValue: Long): ZonedDateTime
Returns a copy of this date-time with the specified field set to a new value.
Returns a copy of this date-time with the specified field set to a new value.
This returns a ZonedDateTime, based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the year, month or day-of-month. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.
In some cases, changing the specified field can cause the resulting date-time to become invalid, such as changing the month from 31st January to February would make the day-of-month invalid. In cases like this, the field is responsible for resolving the date. Typically it will choose the previous valid date, which would be the last valid day of February in this example.
If the field is a ChronoField then the adjustment is implemented here.
The INSTANT_SECONDS field will return a date-time with the specified instant. The zone and nano-of-second are unchanged. The result will have an offset derived from the new instant and original zone. If the new instant value is outside the valid range then a DateTimeException will be thrown.
The OFFSET_SECONDS field will typically be ignored. The offset of a ZonedDateTime is controlled primarily by the time-zone. As such, changing the offset does not generally make sense, because there is only one valid offset for the local date-time and zone. If the zoned date-time is in a daylight savings overlap, then the offset is used to switch between the two valid offsets. In all other cases, the offset is ignored. 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 long) LocalDateTime. The zone is not part of the calculation and will be unchanged. When converting back to ZonedDateTime, if the local date-time is in an overlap, then the offset will be retained if possible, otherwise the earlier offset will be used. If in a gap, the local date-time will be adjusted forward by the length of the gap.
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.

def with(adjuster: TemporalAdjuster): ZonedDateTime
Returns an adjusted copy of this date-time.
Returns an adjusted copy of this date-time.
This returns a new ZonedDateTime, based on this one, with the date-time adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.
A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". Key date-time classes also implement the TemporalAdjuster interface, such as Month and MonthDay. The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.
For example this code returns a date on the last day of July:
```
import static org.threeten.bp.Month.*;
import static org.threeten.bp.temporal.Adjusters.*;

result = zonedDateTime.with(JULY).with(lastDayOfMonth());
```
The classes LocalDate and LocalTime implement TemporalAdjuster, thus this method can be used to change the date, time or offset:
```
result = zonedDateTime.with(date);
result = zonedDateTime.with(time);
```
ZoneOffset also implements TemporalAdjuster however it is less likely that setting the offset will have the effect you expect. When an offset is passed in, the local date-time is combined with the new offset to form an Instant. The instant and original zone are then used to create the result. This algorithm means that it is quite likely that the output has a different offset to the specified offset. It will however work correctly when passing in the offset applicable for the instant of the zoned date-time, and will work correctly if passing one of the two valid offsets during a daylight savings overlap when the same local time occurs twice.
The result of this method is obtained by invoking the TemporalAdjuster#adjustInto(Temporal) method on the specified adjuster passing this as the argument.
This instance is immutable and unaffected by this method call.

Returns a copy of this date-time with the zone ID set to the offset.
This returns a zoned date-time where the zone ID is the same as #getOffset(). The local date-time, offset and instant of the result will be the same as in this date-time.
Setting the date-time to a fixed single offset means that any future calculations, such as addition or subtraction, have no complex edge cases due to time-zone rules. This might also be useful when sending a zoned date-time across a network, as most protocols, such as ISO-8601, only handle offsets, and not region-based zone IDs.
