Sure, but what personally I would expect from MSD is that it will
eventually jump back to MSK, when the time comes -- because it is the thing
I used to see it does. That means, to my mind, MSD in the time zone name
is not for "What Moscow currently use", it is for "changing time between
winter and summer". The zone which is configured in the system is named
MSK, and MSD is only a kind of automatically appearing variation, not the
main thing.
Actually I think it would be better to use MSK, then, because MSK doesn't
include that "D" letter which is for (D)aylight-savings. Certainly it
should me modified accordingly, so that it will be GMT+4 instead of +3 and
won't jump to MSD.

Well, let's call them OWL+1, OWL+2 and so on :-) -- and wait for the
community to invent something reasonable, when we will be able to rename.
