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 NPT
Nepal Time (NPT) is UTC+5:45. It is used in Nepal, all year.
Nepal Time is UTC+5:45 — the only zone in the world offset by three quarters of an hour, set so that noon falls over Kathmandu rather than over the Indian meridian fifteen minutes away. It breaks almost every piece of software that stores offsets in whole or half hours, and it is fifteen minutes ahead of India rather than the round number people assume.
Does this gap change with the seasons?
Neither ACDT nor NPT shifts with the seasons, so this 4.75-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.
