Does daylight saving change WAT to IST?
West Africa Time does not move its clocks at all, so its UTC+1 offset holds every day of the year.
India Standard Time does not move its clocks at all, so its UTC+5:30 offset holds every day of the year.
Is WAT ahead of or behind IST?
WAT is behind IST by 4 hours 30 minutes: when it is 12:00 pm in West Africa, it is 4:30 pm in India. Neither West Africa Time nor India Standard 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. India Standard Time covers the whole of India on a single half hour offset. The identifiers behind them are Africa/Lagos and Asia/Kolkata, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
