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, mostly of two to four letters, identifying the agency concerned. This document lists the abbreviations and their meanings.
The BIPM maintains a similar list at ftp://ftp2.bipm.fr/pub/tai/publication/acronyms.txt, but that only includes current laboratory abbreviations, and does not include special cases such as GPS. The list below is more complete.

This document is derived from the BIPM-maintained abbreviation list at ftp://ftp2.bipm.fr/pub/tai/publication/acronyms.txt. Andrew Main (Zefram) <zefram@fysh.org> added information on historical abbreviations, and made the presentation more consistent.
It is questionable whether this document is copyrightable, due to its essentially functional nature as a collection of raw data. If there is any copyright on the file that this is based on, it is presumably held by the BIPM. Andrew Main does not claim copyright on any part of this document, and hereby places into the public domain any copyrightable aspect of it over which he would otherwise hold the copyright.
No license is required to do anything with public domain materials. To the extent that the BIPM holds copyright on the file that this is based on, reproducing certain aspects of it here is probably fair use.
