FW: Error: end of DST Vienna 1918 is not in Jun

As far as I understand, the text means the following (my German is not perfect):

"1945 daylight saving ended without particular decree, because of the end of the war. That transaction was given by the entrance of the occupation forces and occurred therefore in different parts of the country on different times, for example in Vienna apparently on 2. April 1945."

I though that maybe it can be understood that it doesn't mean only that the daylight saving ended then, but that the occupation forces brought "their time", which was different in different parts of the country, since there were different troops? That is, that every Army had its own time rules? The other problem is that borders between the Armies certainly changed through the time.

On

http://www.magwien.gv.at/english/history/vhisaf.htm

we can find about Vienna: "The political context was no less complicated, the Allied Occupation Forces refusing to accept the Nazis' territorial expansion. The bottom line was that those districts which had existed until 1938 were divided into four Allied zones and the inner-city district was administered by all four powers, as the so-called "Inter-allied Zone". Districts 22 - 26, namely the 97 Lower Austrian communities which had been merged with Vienna in October 1938, were considered to form part of Lower Austria and, hence, came under Soviet control."

Therefore I deliberately pointed only to error in 1918, since it seems too hard point to solve without more information.

Btw, BEV is Austrian "Federal Office of Metrology and Surveying".

so I guess their "?" really means that it's difficult to set some reasonable time. But something has to be set.

There's one more difference between their info and zoneinfo, since one transition happens by them on 1946-10-07 (Monday) although 1946-10-06 as it is in zoneinfo looks better since it's Sunday (like the previous April transition, although it appears that they really almost always moved the clocks on Mondays (I don't know why) before and during WWII).


Best regards,
