Hi again, I looked into this, and as I thought, it's because of Daylight Savings Time. Apparently, until the end of 2013, Russia was using permanent Daylight Savings Time (reference <http://en.wikipedia.org/wiki/Daylight_saving_time_by_country>). In 2014, they returned to Standard Time. As a consequence of this, on Jan 1 2014 12:00am, they subtracted an hour.
WebKit-based browsers attempt to model this appropriately, and as such, in Russian time zones, when you try to create a new Date(2014, 0, 1, 0, 0, 0, 0), it actually gives you 23:00:00 Dec 31 2013. I think we have a reasonable plan to fix this now, and the fix should be available in the next release.
