[tz] Bill to return Russia 11 time zones

Thanks for the heads-up. So the Crimeans will change time zones twice
in the same year? Probably the least of their worries.... Speaking of
which, we should move the entry for Europe/Simferopol closer to that for
Europe/Moscow, to simplify this sort of maintenance.
It is amusing that all changes are supposed to happen at 02:00 Moscow
time. So the folks in Vladivostok are supposed to move their clock
backs at 09:00 local time?
The ITAR-TASS article is a little hazy on the details of the new time
zone boundaries. Most of them seem to be the same as before. Although
the article suggests that we may need to split a zone because of
Zabajkal'skij kraj, I'd like to see a copy of the actual legislation
before going that far. I noodled around on the State Duma website
without finding the law; perhaps they're still working on publication.
In the meantime, I've attached a proposed patch (all in ASCII! :-) for
the parts of the change that seem reasonably clear. I've pushed this to
the experimental repository on github.
I also wonder whether neighboring countries will follow suit. Belarus,
Armenia, and Azerbaijan, for example.
