Method Detail

inStdTimezone

ChronoFunction<Moment,V> inStdTimezone()

Creates a function which can query a Moment in the system timezone.

Note: Usually the function converts the given Moment to a PlainTimestamp and then queries this local timestamp.

Returns:

function with the default system timezone reference, applicable on instances of Moment

Since:

2.0

inTimezone

ChronoFunction<Moment,V> inTimezone(TZID tzid)

Creates a function which can query a Moment in the given timezone.

Note: Usually the function converts the given Moment to a PlainTimestamp and then queries this zonal timestamp.

Parameters:

tzid - timezone id

Returns:

function applicable on instances of Moment

Throws:

IllegalArgumentException - if given timezone cannot be loaded

Since:

in

ChronoFunction<Moment,V> in(Timezone tz)

Creates a function which can query a Moment in the given timezone.

Note: Usually the function converts the given Moment to a PlainTimestamp and then queries this zonal timestamp.

Parameters:

tz - timezone

Returns:

function applicable on instances of Moment

Since:

2.0

atUTC

ChronoFunction<Moment,V> atUTC()

Equivalent to at(ZonalOffset.UTC).

Returns:

function applicable on instances of Moment

Since:
