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.
About MSK
Moscow Time (MSK) is UTC+3. It is used in Moscow and western Russia, with no daylight saving.
Moscow Time is UTC+3 and is fixed year-round: Russia abolished daylight saving in 2014 after a brief and unpopular experiment with permanent summer time. That makes Moscow's relationship with Europe seasonal from Europe's side only — the gap to Berlin is two hours in winter and one in summer, and nothing in Moscow moves to cause it.
Does this gap change with the seasons?
Neither ACDT nor MSK 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.
Frequently asked questions
What time is 9:00 AM ACDT in MSK?

Is MSK ahead of ACDT?
MSK is 7 hours 30 minutes behind ACDT.
Which time zone does this use?
ACDT is UTC+10:30 and MSK is UTC+3. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
