Does daylight saving change GST to BRT?
Gulf Standard Time does not move its clocks at all, so its UTC+4 offset holds every day of the year.
Brasilia 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 BRT?
GST is ahead of BRT by 7 hours: when it is 12:00 pm in Gulf, it is 5:00 am in Brasilia. Neither Gulf Standard Time nor Brasilia 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. Brasilia Time covers Sao Paulo and Rio de Janeiro, fixed since Brazil dropped summer time in 2019. The identifiers behind them are Asia/Dubai and America/Sao_Paulo, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
