public final class ZonalClock
extends java.lang.Object
Represents a clock which yields the current local time according to a timezone.
This class is immutable as long as the underlying implementations of time source and time zone are.
| Constructor and Description |
|---|
ZonalClock(TimeSource<?> timeSource,
java.lang.String tzid)
Constructs a new clock which can yield the current local time in
given timezone.
|
ZonalClock(TimeSource<?> timeSource,
TZID tzid)
Constructs a new clock which can yield the current local time in
given timezone.

public ZonalClock(TimeSource<?> timeSource, TZID tzid)
Constructs a new clock which can yield the current local time in given timezone.
Most users have no need to directly call this constructor. It is
mainly designed for being called by dedicated expressions like
SystemClock.inZonalView(tzid) etc.

Ermittelt das aktuelle Datum in der assoziierten Zeitzone.
Das Ergebnis hängt genau dann dynamisch von der assoziierten Zeitzone ab, wenn die System-Zeitzone vorliegt.
public PlainTimestamp now()
Gets the current timestamp in the associated timezone.
The result dynamically depends on the associated timezone meaning if and only if the underlying timezone is the system timezone.
public <T extends ChronoEntity<T>> T now(Chronology<T> chronology)
Gets the current timestamp in the associated timezone and given chronology.
The result always dynamically depends on the associated timezone meaning if the underlying timezone data change then the result will also change by next call.
Code example:
System.out.println(SystemClock.inLocalView().now(PlainTime.axis())); // local wall time
T - generic type of chronologychronology - chronology to be usedjava.lang.IllegalArgumentException - if given chronology requires a calendar variantpublic <T extends CalendarVariant<T>> T now(CalendarFamily<T> chronology, java.lang.String variant, StartOfDay startOfDay)
Gets the current timestamp in the associated timezone and given chronology taking into account given calendar variant and start of day.
The result always dynamically depends on the associated timezone meaning if the underlying timezone data change then the result will also change by next call.
Code example:
HijriCalendar hijriDate =
CLOCK.now(
HijriCalendar.family(),
HijriCalendar.VARIANT_UMALQURA,
StartOfDay.EVENING);
System.out.println(hijriDate); // AH-1436-10-02[islamic-umalqura]
Note that this example is even true if the current timestamp is 2015-07-17T18:00 which would normally map to AH-1436-10-01 (if the clock time is not considered). Reason is that the islamic day starts on the evening of the previous day.
