Android Timezone Turkey Gmt

For 2016 Turkish Government decided to stay GMT+3 timezone to save daylight, but on android: Calendar calendar = Calendar.getInstance(); TimeZone tz = TimeZone.getTimeZone('UTC')

Solution 1:

See the release note of tzdb-database for version 2016g:

Release 2016g - 2016-09-13 08:56:38 -0700

Changes to future time stamps

Turkey switched from EET/EEST (+02/+03) to permanent +03,
effective 2016-09-07.  (Thanks to Burak AYDIN.)  
Use "+03" rather than an invented abbreviation for the new time.

Obviously, your Android device still uses an outdated timezone version. Actually you have following options to proceed:

• Wait for a new Android version (not attractive, not recommended).
• Use another external library like Joda-Time-Android or my library Time4A which already use 2016h (Threeten-ABP is still behind, actually on 2016e).
• Or write your own hack using fixed offsets for Turkey, for example TimeZone.getTimeZone("GMT+03")
