Why people convert Doha to Istanbul time

About AST (Arabia Standard Time)
Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen. None of these countries observes daylight saving time, so the offset never changes. The abbreviation collides with Atlantic Standard Time (UTC-04:00) used in eastern Canada and the Caribbean; this page covers the Arabian peninsula meaning. Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
About TRT (Turkey Time)
Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.
