I might be missing if this issue was discussed before in here but Turkish government officially announced in 16.03.2016 (with 2016/8589 Law/Decision Number) that clock changes have been published in the official gazette (T.C. Resmi Gazete);

 - In 27 March 2016 at 03:00, the clock forwards one hour (04:00)
 - In 30 October 2016 at 04:00, the clock goes back one hour (03:00)
