Lazia, 19 October 2019 — The National Convention of 2019 has approved measures for Mahuset to adopt Coordinated Universal Time (UTC) in place of the Greenwich Mean Time (GMT) it had used for the previous seven and a half years.

The two keep the same clock in practice, but differ in kind: GMT is a time zone, whereas UTC is a time standard — the basis for civil time and time zones the world over, and used as a local time by no country at all. Until 1972 Greenwich Mean Time served as Universal Time, the basis of the 24-hour zone system in use today; thereafter it was supplanted by Coordinated Universal Time.

UTC is reckoned from two ingredients: International Atomic Time, which combines the output of some 400 highly precise atomic clocks to fix the exact rate at which clocks should tick, and Universal Time (UT1), or astronomical time, which tracks the Earth’s rotation and so measures the true length of a day. The combination yields a far more accurate result than GMT afforded. Despite UTC’s adoption by the international community and the precision it brings, Mahuset had persisted with the less accurate Greenwich Mean Time in its operations until now.
