Bug Description

Russia has shifted again for winter time, and difference betwen UTC and local time in Moscow now is +3 hr, but ALL the systems and servers with time zone databases (including Apple) are still sure that Russia is UTC+4. The Stellarium takes the real time from my computer (and it is correct, i.e it is 18:12 in Moscow now), but it thinks that 18:12 MSK = 14:12 UTS, though it is already 15:12 UTC!!!! Now it shows me the sky events which has happened ONE HOUR AGO! For example, the today sunset in Moscow is in 20 minutes, at 18:28 local time = 15:28 UTS. But the Stellarium will show me this sunset one hour later, only when there is 19:28 loc.time at my computer.

Would it be better to switch OFF the automatic link to time-zone servers and to allow a user himself to set the difference betwen his local time and UTC?

PS: Russia's idiotic jumps from winter to summer time systems for latest 5 years has f**cked everybody's mind, and we shall not hope that servers will follow soon all this crazy changes.

Stellarium doesn't manage time zones and he use TZ info from operating system. If your OS has wrong data about time zones you should update this data. I'm living in the Russian and I have correct tzdata file and I don't have problems, which you described above.

I can NOT update this data! Because the data is not in my personal file on personal computer, but my computer takes it ready from common tz-server. Maybe some worldwide companies (i.e. Microsoft or Asus) use the tz-servers with correct data. But A LOT of software and hardware brands use incorrect servers. Including all the millions of Apple devices in Russia are linked to tz-server 'time.europe.appe.com' with wrong UTC+4. So Stellarium uses this Apple's mistaken data, and I can not change it. Do you think, that I am able to hack Apple servers??? Instead I wish Stellarium either use the correct tz-servers (not from my system) or allow me to set the UTC-local differense manually.

Look at the screenshot: it gives UTC+4 instead of UTC+3, and I CAN NOT change it!! Neither in my computer, nor in Stellarium settings. Instead I have to scroll from real 19:55 Moscow time (true UTC+3) ahead to fantastic 20:55 (false UTC+4). Because Stellarium shows the real pucture (as for current 19-55) only one hour later at 20:55. And if I click "go to current time', it indicates real 19:55 at its timeline (because now it is 19:55 in Msk, and sure I set my comp for it), but shows the false sky picture as it were one hour earlier.

NTP server and TZ data is DIFFERENT data! All TZ data stored on the local computers - within registry on Windows and files on Linux as example. Changing TZ data for OS X - http://apple.stackexchange.com/questions/150606/change-timezone-in-russia-26-10-14-in-mac-os-x-10-9-5 (just a 10 seconds with Google). Is it really difficult for you? Plus I have one Apple iPad and I have correct TZ info and I doesn't has any troubles with Stellarium.

For case If setting correct TZ is hard task for you then just open Time Zone plugin withing Stellarium and change TZ!
