Estonia
From Paul Eggert (2016-03-18):
The 1989 transition is from USSR act No. 227 (1989-03-14).
From Peter Ilieve (1994-10-15):
A relative in Tallinn confirms the accuracy of the data for 1989 onwards
[through 1994] and gives the legal authority for it,
a regulation of the Government of Estonia, No. 111 of 1989....
From Peter Ilieve (1996-10-28):
[IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,
but a relative confirms that Estonia still switches at 02:00s, writing:]
"I do not [know] exactly but there are some little different
(confusing) rules for International Air and Railway Transport Schedules
conversion in Sunday connected with end of summer time in Estonia....
A discussion is running about the summer time efficiency and effect on
human physiology. It seems that Estonia maybe will not change to
summer time next spring."
From Peter Ilieve (1998-11-04), heavily edited:
The 1998-09-22 Estonian time law
http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390
refers to the Eighth Directive and cites the association agreement between
the EU and Estonia, ratified by the Estonian law (RT II 1995, 22-27, 120).
I also asked [my relative] whether they use any standard abbreviation
for their standard and summer times. He says no, they use "suveaeg"
(summer time) and "talveaeg" (winter time).
From The Baltic Times <https://www.baltictimes.com/> (1999-09-09)
via Steffen Thorsen:
This year will mark the last time Estonia shifts to summer time,
a council of the ruling coalition announced Sept. 6....
But what this could mean for Estonia's chances of joining the European
Union are still unclear. In 1994, the EU declared summer time compulsory
for all member states until 2001. Brussels has yet to decide what to do
after that.
From Mart Oruaas (2000-01-29):
Regulation No. 301 (1999-10-12) obsoletes previous regulation
No. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all
the year round. The regulation is effective 1999-11-01.
From Toomas Soome (2002-02-21):
The Estonian government has changed once again timezone politics.
Now we are using again EU rules.
From Urmet Jänes (2002-03-28):
The legislative reference is Government decree No. 84 on 2002-02-21.
