Datetime conversion is a switch from a numeric datetime to a complex datetime and the reverse.

• Convert a date from milliseconds:

  long milliSinceEpoch = 434931330000L;
  Instant instant = Instant.ofEpochMilli(milliSinceEpoch);
  ZonedDateTime zdt = ZonedDateTime.ofInstant(instant, ZoneId.of('Z'));
  		

• Convert a date to milliseconds:

  ZonedDateTime zdt =
          ZonedDateTime.of(1983, 10, 13, 22, 15, 30, 0, ZoneId.of('Z'));
  long milliSinceEpoch = zdt.toInstant().toEpochMilli();
