Does daylight saving change GST to AWST?
Gulf Standard Time does not move its clocks at all, so its UTC+4 offset holds every day of the year.
Australian Western Time does not move its clocks at all, so its UTC+8 offset holds every day of the year.
Is GST ahead of or behind AWST?
GST is behind AWST by 4 hours: when it is 12:00 pm in Gulf, it is 4:00 pm in Australian Western. Neither Gulf Standard Time nor Australian Western 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. Australian Western Time covers Perth and Western Australia, which stopped moving its clocks in 2009. The identifiers behind them are Asia/Dubai and Australia/Perth, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
