  • Method Details

    • inStdTimezone

      public ChronoOperator<Moment> inStdTimezone()

      Creates an operator which can adjust a Moment in the system timezone.

      Note: Usually the operator converts the given Moment to a PlainTimestamp then processes this local timestamp and finally converts the result back to a new Moment. A special case are incrementing and decrementing of (sub-)second elements which eventually operate directly on the UTC timeline.

      Returns:
      operator with the default system timezone reference, applicable on instances of Moment

    • inTimezone

      public final ChronoOperator<Moment> inTimezone​(TZID tzid)

      Creates an operator which can adjust a Moment in the given timezone.

      Note: Usually the operator converts the given Moment to a PlainTimestamp then processes this local timestamp and finally converts the result back to a new Moment. A special case are incrementing and decrementing of (sub-)second elements which eventually operate directly on the UTC timeline.

      Parameters:
      tzid - timezone id
      Returns:
      operator with the given timezone reference, applicable on instances of Moment
      Throws:
      IllegalArgumentException - if given timezone cannot be loaded

    • in

      public final ChronoOperator<Moment> in​(Timezone tz)

      Creates an operator which can adjust a Moment in the given timezone.

      Note: Usually the operator converts the given Moment to a PlainTimestamp then processes this local timestamp and finally converts the result back to a new Moment. A special case are incrementing and decrementing of (sub-)second elements which eventually operate directly on the UTC timeline.

      Parameters:
      tz - timezone
      Returns:
      operator with the given timezone reference, applicable on instances of Moment

    • atUTC

      public final ChronoOperator<Moment> atUTC()

      Equivalent to at(ZonalOffset.UTC).

      Returns:
      operator for UTC+00:00, applicable on instances of Moment
      Since:
      1.2

      at(ZonalOffset)

    • at

      public final ChronoOperator<Moment> at​(ZonalOffset offset)

      Creates an operator which can adjust a Moment at the given timezone offset.

      Note: Usually the operator converts the given Moment to a PlainTimestamp then processes this local timestamp and finally converts the result back to a new Moment. A special case are incrementing and decrementing of (sub-)second elements which eventually operate directly on the UTC timeline.

      Parameters:
      offset - timezone offset
      Returns:
      operator with the given timezone offset, applicable on instances of Moment
      Since:
      1.2
