Georgia abandoning Soviet-era decree time, back to zonal time

27.06.2004, 02.36

TBILISI, June 27 (Itar-Tass) - Georgia is abandoning the Soviet-era
special, or decreed, time and is switching back to its zonal time
as of Sunday, June 27.

In practical terms, this means that it will now have the same time
as Russias Moscow zone and will be three hours ahead of London
instead of the former four hours, and two hours ahead of Paris and
Berlin instead of the former three.

The reverting to the zonal time follows a recent decree by President
Mikhail Saakashvili saying the decision on it was taken with due
regard of Georgias geographic position, the European integration
process, and proposals by the national department for standards and

The so-called decreed time took effect all across the former USSR
from Kamchatka through to Belarus and from the Artic Islands through
to southern Turkmenistan June 16, 1930.

The measure was aimed at a better us of daylight.

Unlike daylight saving time (DST), the decreed time did not shift
and was pegged on the principle of zonal time plus an hour round
the year.

As of 1981, however, the DST was also introduced in the USSR, which
meant that from April through October the formula would look like
the zonal time plus one hour of the decreed time plus one hour of
the DST.

Most countries of the former USSR dropped the decreed timed by now
and reverted to their zonal time. Russia is one of a few exceptions.
