Datetime Pieces

Serverless Stack

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.

• Create a complex datetime from pieces:

  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:

  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();
