Method Details

toZonedDateTime

ColumnSource<ZonedDateTime> toZonedDateTime(ZoneId zone)

Convert this source to a ZonedDateTime source at the specified zone.

Parameters:

zone - the time zone

Returns:

a view of this source as a ZonedDateTime

toLocalDate

ColumnSource<LocalDate> toLocalDate(ZoneId zone)

Convert this source to a LocalDate source at the specified zone.

Parameters:

zone - the time zone

Returns:

a view of this source as a LocalDate

toLocalTime

ColumnSource<LocalTime> toLocalTime(ZoneId zone)

Convert this source to a LocalTime source at the specified zone.

Parameters:

zone - the time zone
