Expand description

A shift (in seconds) from the Unix epoch (1970-01-01 00:00:00) to a base date that is a multiple of a 400-year leap cycle.

Used in Instant -> UtcDateTime conversion.

The date we’re using is 2000-03-01 00:00:00, for two reasons:

  1. It’s a multiple of 400, to make it easier to work with leap years
  2. We’re also shifting the month to 1st March, so that the extra day on leap years is added to the last month (Feb), not in the middle of a year (makes some calculations easier)
