Java ZonedDateTime class is an immutable representation of a date-time with a time-zone. It inherits Object class and implements the ChronoZonedDateTime interface.

ZonedDateTime class is used to store 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.

Method Description
String format(DateTimeFormatter formatter) It is used to format this date-time using the specified formatter.
int get(TemporalField field) It is used to get the value of the specified field from this date-time as an int.
ZoneId getZone() It is used to get the time-zone, such as 'Asia/Kolkata'.
ZonedDateTime withZoneSameInstant(ZoneId zone) It is used to return a copy of this date-time with a different time-zone, retaining the instant.
static ZonedDateTime now() It is used to obtain the current date-time from the system clock in the default time-zone.
static ZonedDateTime of(LocalDate date, LocalTime time, ZoneId zone) It is used to obtain an instance of ZonedDateTime from a local date and time.
ZonedDateTime minus(long amountToSubtract, TemporalUnit unit) It is used to return a copy of this date-time with the specified amount subtracted.
ZonedDateTime plus(long amountToAdd, TemporalUnit unit) It is used to return a copy of this date-time with the specified amount added.
