Obtains an instance of ZonedDateTime from a temporal object.
Obtains an instance of ZonedDateTime from a temporal object.
A TemporalAccessor represents some form of date and time information.
This factory converts the arbitrary temporal object to an instance of ZonedDateTime.
The conversion will first obtain a ZoneId. It will then try to obtain an instant.
If that fails it will try to obtain a local date-time.
The zoned date time will either be a combination of ZoneId and instant,
or ZoneId and local date-time.
This method matches the signature of the functional interface TemporalQuery
allowing it to be used in queries via method reference, ZonedDateTime::from.

Obtains the current date-time from the specified clock.
Obtains the current date-time from the specified clock.
This will query the specified clock to obtain the current date-time. The zone and offset will be set based on 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.

the current date-time, not null
Obtains the current date-time from the system clock in the specified time-zone.
Obtains the current date-time from the system clock in the specified time-zone.
This will query the system clock to obtain the current date-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.
the zone ID to use, not null
the current date-time using the system clock, not null
Obtains the current date-time from the system clock in the default time-zone.
Obtains the current date-time from the system clock in the default time-zone.
This will query the system clock in the default
time-zone to obtain the current date-time.
The zone and offset will be set based on 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.

Obtains an instance of ZonedDateTime from a year, month, day,
hour, minute, second, nanosecond and time-zone.
Obtains an instance of ZonedDateTime from a year, month, day,
hour, minute, second, nanosecond and time-zone.
This creates a zoned date-time matching the local date-time of the seven specified fields as closely as possible. Time-zone rules, such as daylight savings, mean that not every local date-time is valid for the specified zone, thus the local date-time may be adjusted.
The local date-time is resolved to a single instant on the time-line.
This is achieved by finding a valid offset from UTC/Greenwich for the local
date-time as defined by the rules of the zone ID.
In most cases, there is only one valid offset for a local date-time. In the case of an overlap, when clocks are set back, there are two valid offsets. This method uses the earlier offset typically corresponding to "summer".
In the case of a gap, when clocks jump forward, there is no valid offset. Instead, the local date-time is adjusted to be later by the length of the gap. For a typical one hour daylight savings change, the local date-time will be moved one hour later into the offset typically corresponding to "summer".
This method exists primarily for writing test cases.
Non test-code will typically use other methods to create an offset time.
LocalDateTime has five additional convenience variants of the
equivalent factory method taking fewer arguments.
They are not provided here to reduce the footprint of the API.
the year to represent, from MIN_YEAR to MAX_YEAR
the month-of-year to represent, from 1 (January) to 12 (December)

the minute-of-hour to represent, from 0 to 59
the second-of-minute to represent, from 0 to 59
the nano-of-second to represent, from 0 to 999,999,999

the offset date-time, not null
DateTimeException if the value of any field is out of range, or

Obtains an instance of ZonedDateTime from a local date-time.
Obtains an instance of ZonedDateTime from a local date-time.

Obtains an instance of ZonedDateTime from the instant formed by combining
the local date-time and offset.
Obtains an instance of ZonedDateTime from the instant formed by combining
the local date-time and offset.
This creates a zoned date-time by combining
the LocalDateTime and ZoneOffset.
This combination uniquely specifies an instant without ambiguity.
Converting an instant to a zoned date-time is simple as there is only one valid offset for each instant. If the valid offset is different to the offset specified, the the date-time and offset of the zoned date-time will differ from those specified.
If the ZoneId to be used is a ZoneOffset, this method is equivalent
to ZoneId).

Obtains an instance of ZonedDateTime from an Instant.
Obtains an instance of ZonedDateTime from an Instant.
This creates a zoned date-time with the same instant as that specified.
Calling #toInstant() will return an instant equal to the one used here.

Obtains an instance of ZonedDateTime from a local date-time

Obtains an instance of ZonedDateTime from a local date-time
using the preferred offset if possible.
The local date-time is resolved to a single instant on the time-line.
This is achieved by finding a valid offset from UTC/Greenwich for the local
date-time as defined by the rules of the zone ID.
In most cases, there is only one valid offset for a local date-time. In the case of an overlap, where clocks are set back, there are two valid offsets. If the preferred offset is one of the valid offsets then it is used. Otherwise the earlier valid offset is used, typically corresponding to "summer".
In the case of a gap, where clocks jump forward, there is no valid offset. Instead, the local date-time is adjusted to be later by the length of the gap. For a typical one hour daylight savings change, the local date-time will be moved one hour later into the offset typically corresponding to "summer".

This creates a zoned date-time ensuring that the offset is valid for the local date-time according to the rules of the specified zone. If the offset is invalid, an exception is thrown.
