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...

Time::TT::Agencies - list of Terran horological agencies
Precision timekeeping on Terra is a complex task undertaken by a group of about seventy agencies around the planet, mostly national metrological laboratories. The time scales that they produce are conventionally labelled using short abbreviations, mo...

Time::TT::OffsetKnot - MJD/offset tuple for realisations of TT
This class assists in implementing a realisation of Terrestrial Time (TT) by interpolation using the "Time::TT::InterpolatingRealisation" class. Many such time scales are defined by tables of data giving the difference between TAI and the time scale ...

Time::TT::Realisation - realisation of Terrestrial Time (base class)
Terrestrial Time (TT) is a platonic time scale, consisting of the time axis of a relativistic reference frame located on the Terran geoid. It is not directly accessible for practical use. Instead, it must be realised by the use of atomic clocks and o...

Time::TT::InterpolatingRealisation - TT realised by interpolation
This class implements a realisation of Terrestrial Time (TT) by interpolation between known points of correlation between the realisation and International Atomic Time (TAI). See Time::TT::Realisation for the interface....
