Time shown on the proflie page is one hour off (outdated timezones database version?)

The only relevant discussion I found in this category was closed a while ago, but the problem is still ongoing (for me at least).

I know for sure that the timezone is set correctly on the system, and multiple websites detect it properly (by offset).
However, the SG account page, while recognizing the timezone itself, applies an incorrect offset when returning the value.
This does appear to be caused by the messed up Russian legislation by an outdated TZ database, as currently the site behaves as if Moscow has the eternal summer going on, whereas (starting from Oct 26 of 2014) it is now actually winter all year round.

Whenever I try to create a giveaway, and set the start time to "Now", SG detects the local time correctly, but immediately after this does not allow saving or reviewing the GA, claiming that "Giveaway must start after the current time" (see the attached image). It goes through only if I add an extra hour. This only started after the SGv2 update.
