If Turkey actually changes its time zones or daylight-saving rules please let us know. I hope they give us plenty of warning (such as a year or more); otherwise, their cell phones and/or computers will likely be off. One minor point. The text says "Saatlerini değiştirmeyen en büyük ülkeler Çin, Hindistan ve Japonya" which Google translates as "The largest countries that do not change their clocks are China, India and Japan." Using the Wikipedia list of countries by population[1], the ten most populous countries that do not observe daylight saving time are China, India, Indonesia, Pakistan, Brazil, Nigeria, Bangladesh, Russia, Japan, and Ethiopia, in that order.
