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