ACS::Time | value |
A structure to hold an epoch. This structure represents a particular date and time.
An epoch is encoded in units of 100 nanoseconds, i.e. seconds, since October 15, 1582 at 00:00:00. It is stored in an unsigned 64-bit integer, giving it a range of more than 58,454 years. The last representable date is around March 11, 60038. This same encoding is used by the CORBA and X/Open DCE Time Services.
October 15, 1582 is the beginning of the Gregorian calendar. Before then dates are represented in the Julian Calendar. This implies a Julian Calendar even for times when nobody knew about it (proleptic Julian Calendar). There is a gap of ten days between October 4, 1582 and October 15, 1582 ordered by Pope Gregory to achieve better agreement between the civil and the astronomical calendar.
