Rules Russia were recently fixed to have transition from DST at 3:00
local time, so zdump's behaviour is expected.
Wikipedia links to
(Act of the Cabinet of Ministers of the Republic of Belarus
from 25.03.1992 N 157)
which says clocks were to be moved forward at 2:00 on last Sunday of
March and backward at 3:00 on last Sunday of September (the same as
previous USSR and contemporary Russian regulations). So it looks like
March 1992 transition for Europe/Minsk is incorrect.
I suspect that lines
2:00 1:00 EEST 1991 Sep 29 2:00s
2:00 - EET 1992 Mar 29 0:00s
2:00 1:00 EEST 1992 Sep 27 0:00s
should be removed from Europe/Minsk.
