Does daylight saving change WAT to GMT?
West Africa Time does not move its clocks at all, so its UTC+1 offset holds every day of the year.
Greenwich Mean Time does not move its clocks at all, so its UTC+0 offset holds every day of the year.
Is WAT ahead of or behind GMT?
WAT is ahead of GMT by 1 hour: when it is 12:00 pm in West Africa, it is 11:00 am in GMT. Neither West Africa Time nor Greenwich Mean Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
West Africa Time covers Lagos, Kinshasa, Luanda and Douala, the most populous zone in Africa. Greenwich Mean Time covers identical to UTC as a clock reading, and a separate thing as a standard. The identifiers behind them are Africa/Lagos and Etc/GMT, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
