NAME ^

Time::TT::Agencies - list of Terran horological agencies

DESCRIPTION ^

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.
