Decree time

Decree time (Russian: Декретное время) refers to the changes introduced to the USSR time system by a Sovnarkom decree of 16 June 1930 at 02:00. By this decree, all clocks in the Soviet Union were permanently shifted at 03:00 (one hour ahead of standard time) for each timezone.

It is independent from Daylight Saving Time, which was introduced in the USSR much later, in 1981. In fact, with both time shifts in effect, summer time was two hours ahead of standard time in the USSR.

From 1982 to 1986, decree time was gradually abolished by the USSR government in 30 oblasts and autonomous Republics of the Russian SFSR. In the late 1980s, it was further abolished in the Baltic republics, Ukraine and Moldavia, followed by the entire territory of the Soviet Union in March 1991 (eight months before its dissolution).

On 23 October 1991, the Supreme Soviet of the Russian SFSR ruled to restore decree time in Russia. It was restored on 19 January 1992 at 02:00, with the following exemptions:

Most of these exemptions are equivalent to abolition of decree time in corresponding territories. At present all these federal subjects use the exemptions.

In 1992 decree time was restored in Armenia, Azerbaijan, Georgia, Kazakhstan, and the former Central Asia republics as well.
