- Handling a -8h 30m gap: ACST and Casablanca have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Casablanca is 12:30 AM in ACST.

About ACST (Australian Central Standard Time)
Australian Central Standard Time (ACST) is the half-hour offset of UTC+09:30 used across South Australia and the Northern Territory, taking in Adelaide and Darwin. South Australia moves to Australian Central Daylight Time (ACDT, UTC+10:30) from the first Sunday in October to the first Sunday in April, but the Northern Territory does not observe daylight saving — so Adelaide and Darwin sit 30 minutes apart in summer and level with each other in winter. The half-hour offset means Adelaide is 30 minutes behind Sydney in winter and level with it during daylight saving, which regularly catches out travellers and meeting planners.
About WET (Western European Time)
Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).
