I think that the question we need to answer is: should the Russian 
time zones now have the "isdst" flag permanently set to 0 (for 
standard time), or permanently set to 1 (for daylight savings 
time)?  I don't know what should be the case, but currently the 
Russian time zones have isdst=0.

According to the output from "zdump -v Europe/Moscow", the 
last transition was from {isdst=0, gmtoff=10800} to {isdst=0, 
tzoff=14400}, on 27 Mar 2011.  This transition corresponds to a 
one-hour jump in standard time, without either entering or leaving 
daylight savings time.

Obviously, the Russian time zones should also have the correct 
offset from UTC, and I believe that they are correct in that
