Does daylight saving change GST to MSK?
Gulf Standard Time does not move its clocks at all, so its UTC+4 offset holds every day of the year.
Moscow Time does not move its clocks at all, so its UTC+3 offset holds every day of the year.
Is GST ahead of or behind MSK?
GST is ahead of MSK by 1 hour: when it is 12:00 pm in Gulf, it is 11:00 am in Moscow. Neither Gulf Standard Time nor Moscow Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Gulf Standard Time covers Dubai, Abu Dhabi and Muscat. Moscow Time covers Moscow and western Russia, fixed since 2014. The identifiers behind them are Asia/Dubai and Europe/Moscow, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
