Thanks for the reference and for the correction.  It also appears to
me that the current data are wrong for 1945 in Vienna, and for 1980 in
Austria.  The BEV seems to be saying that in Vienna daylight-saving
was observed for only 10 days in 1945, allegedly.  So I'll propose
something like the following patch to the "europe" file in my next
batch of changes, which is due soon.
