Enumeration Type Documentation

TimestampReference

enum TimestampReference

The reference point in time.

With this enum we define the reference point of a timestamp. Since the internal data structure uses Julian day as the starting point when counting the elapsed microseconds, with the help of this enum the reference can be changed when receiving a timestamp (i.e. DateTime::toTimestamp()) and be converted back to Julian day reference point when setting a timestamp (i.e. DateTime::set(timestamp_t, TimestampReference))

Enumerator
MicroSecondsSinceJulianDateOrigin	Reference point in time is noon on Monday, January 1, 4713 BC (Julian day)
MicroSecondsSinceUnixTimeOrigin	Reference point in time is midnight on Thursday, 1 January 1970 AC (Unix time)
