Trabzon is on Turkish time, UTC+3, like the rest of the country. What changes from city to city is the daylight.
Turkey keeps one time zone across roughly 1,600 km, so the clock in Trabzon matches Istanbul exactly while the sun rises at a different moment. The figures above are calculated for Trabzon's own coordinates and update as the date changes.
Trabzon is the main city of Turkey's eastern Black Sea coast, backed by steep green mountains and a great deal more rain than the rest of the country. It was the capital of the Empire of Trebizond and a terminus of the Silk Road.
Being well to the east, Trabzon gets its sunrise around forty minutes before Istanbul does, on the same clock.
Trabzon is in the Black Sea region of Turkey.
