About AEST
Australian Eastern Standard Time (AEST) is UTC+10. It is used in Sydney, Melbourne and Brisbane in the southern winter.
Australian Eastern Standard Time is UTC+10, covering Sydney, Melbourne, Brisbane and Canberra in winter. The complication is that Queensland does not observe daylight saving while New South Wales and Victoria do — so from October to April, Brisbane stays on AEST while Sydney moves to AEDT, and two cities on the same coast are an hour apart for half the year.
About WAT
West Africa Time (WAT) is UTC+1. It is used in Nigeria, Cameroon, Angola and much of central and western Africa.
West Africa Time is UTC+1 all year, with no daylight saving anywhere that uses it. It covers Lagos, Kinshasa and Luanda — a very large population on a single fixed offset. It matches Central European Time in winter and falls an hour behind it in summer, which means a standing Europe–Nigeria meeting moves twice a year at the European end and never at the African one.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on AEST switches to AEDT (UTC+11) from October to April. So the 9-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
WAT does not shift, so the whole change comes from one side. A recurring meeting fixed in WAT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
