About GMT and WAT
GMT (Greenwich Mean Time) covers UK, Ireland, Iceland, and Portugal and is anchored to the IANA zone Europe/London. It observes daylight saving time, so the offset shifts by one hour twice a year.
WAT (West Africa Time) covers Nigeria, Cameroon, and Angola via Africa/Lagos. It does not observe daylight saving time.
Because at least one of these zones uses DST, the time difference between GMT and WAT is not constant — it shifts by an hour during the spring and autumn DST transitions. The hour grid below recomputes the difference for any specific date you click, using the IANA rules baked into your browser.
