About EAT
East Africa Time (EAT) is UTC+3. It is used in Kenya, Tanzania, Ethiopia, Uganda and Somalia.
East Africa Time is UTC+3 and fixed. Nairobi, Addis Ababa and Dar es Salaam all keep it. Ethiopia additionally uses a clock that counts from dawn rather than midnight for everyday purposes, six hours off the international one, so a time given locally in Addis may need converting twice rather than once.
About ACDT
Australian Central Daylight Time (ACDT) is UTC+10:30. It is used in Adelaide in summer.
Australian Central Daylight Time is UTC+10:30, what South Australia keeps from October to April. Darwin stays on ACST through the summer, so for those months two cities in the same nominal zone are an hour apart — the only reason to be precise about which of the two abbreviations a meeting invitation carries.
Does this gap change with the seasons?
Neither EAT nor ACDT shifts with the seasons, so this 7.5-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.
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.
