Eşgüdümlü Evrensel Zaman ve Php Dünya Saatleri (World Clock) Uygulaması

Eşgüdümlü Evrensel Zaman

UTC (Coordinated Universal Time), yani eşgüdümlü evrensel zaman (yahut saat) anlamına gelir. Teknik olarak aynı olmasa da, GMT ile aynı anlamda da kullanıldığı olur.

İngilizce kısaltma CUT (Coordinated Universal Time) ve Fransızca kısaltma TUC (Temps universel coordonné) arasında seçim yapılamadığından orta yol olarak UTC kısaltması seçilmiştir. İngiltere’de Greenwich’ten geçen meridyen referans kabul edilerek hesaplanır.

Türkiye Moskova Zaman Dilimi’ndedir; bu yüzden Türkiye saati UTC+2, yani UTC’den iki saat ileridedir. Fakat saatlerin bir saat ileri alınmasıyla Türkiye saati UTC+3’tür.
