Comment 2 for bug 802778

Test case for Russia abandoning DST in June of 2011, timezone for the test is "Europe/Moscow":

Incorrect result with 2011g showing active DST transitions for Russia in 2011 for both March and October:

$ zdump -v Europe/Moscow | grep 2011
Europe/Moscow Sat Mar 26 22:59:59 2011 UTC = Sun Mar 27 01:59:59 2011 MSK isdst=0 gmtoff=10800
Europe/Moscow Sat Mar 26 23:00:00 2011 UTC = Sun Mar 27 03:00:00 2011 MSD isdst=1 gmtoff=14400
Europe/Moscow Sat Oct 29 22:59:59 2011 UTC = Sun Oct 30 02:59:59 2011 MSD isdst=1 gmtoff=14400
Europe/Moscow Sat Oct 29 23:00:00 2011 UTC = Sun Oct 30 02:00:00 2011 MSK isdst=0 gmtoff=10800

Correct result with 2011h showing the October transition has been removed (note that the March transition remains for historical purposes):

$ zdump -v Europe/Moscow | grep 2011
Europe/Moscow Sat Mar 26 22:59:59 2011 UTC = Sun Mar 27 01:59:59 2011 MSK isdst=0 gmtoff=10800
Europe/Moscow Sat Mar 26 23:00:00 2011 UTC = Sun Mar 27 03:00:00 2011 MSK isdst=0 gmtoff=14400

And checking next year (2012) with 2011h we see that there are no transitions at all:

$ zdump -v Europe/Moscow | grep 2012

(no result)
