Method Detail

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:

java.lang.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

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
