Comment 3 for bug 1431926

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!
