Date::JD - conversion between flavours of Julian Date

For date and time calculations it is convenient to represent dates by a simple linear count of days, rather than in a particular calendar. This is such a good idea that it has been invented several times. If there were a single such linear count then...

DateTime::Format::Epoch::JD - Convert DateTimes to/from Julian Days

This module can convert a DateTime object (or any object that can be converted to a DateTime object) to the Julian Day number. This is the number of days since noon U.T.C. on January 1, 4713 B.C. (Julian calendar). This time scale was originally prop...

Time::TT - Terrestrial Time and its realisations

Terrestrial Time (TT) is a time scale representing time on the surface of Terra. Specifically, it is the proper time experienced by a clock located on the rotating geoid (i.e., at sea level). It is indirectly the basis for Terran civil timekeeping, v...
