Datetime Pieces [_datetime_pieces]

Datetime representations often contain the data to extract individual datetime pieces such as year, hour, timezone, and so on. Use individual pieces of a datetime to create a complex datetime, and use a complex datetime to extract individual pieces.

Datetime Pieces Examples [_datetime_pieces_examples]

Create a complex datetime from pieces:

painless

int year = 1983;
int month = 10;
int day = 13;
int hour = 22;
int minutes = 15;
int seconds = 30;
int nanos = 0;
ZonedDateTime zdt = ZonedDateTime.of(
        year, month, day, hour, minutes, seconds, nanos, ZoneId.of('Z'));

Extract pieces from a complex datetime:

painless

ZonedDateTime zdt =
        ZonedDateTime.of(1983, 10, 13, 22, 15, 30, 100, ZoneId.of(tz));
int year = zdt.getYear();
int month = zdt.getMonthValue();
int day = zdt.getDayOfMonth();
int hour = zdt.getHour();
int minutes = zdt.getMinute();
int seconds = zdt.getSecond();
int nanos = zdt.getNano();
