About ACST
Australian Central Standard Time (ACST) is UTC+9:30. It is used in Adelaide and Darwin in winter.
Australian Central Standard Time is UTC+9:30, half an hour behind the eastern states rather than a whole hour, which surprises people every time. South Australia moves to daylight saving in October and the Northern Territory does not, so Adelaide and Darwin share this offset for half the year and are an hour apart for the other half.
About PKT
Pakistan Standard Time (PKT) is UTC+5. It is used in Pakistan, all year.
Pakistan Standard Time is UTC+5 and does not change through the year — daylight saving has been tried twice and abandoned twice. It sits half an hour behind India, which is the only pair of neighbouring countries in the region separated by a half-hour step rather than a whole one, and a common source of missed calls across that border.
Does this gap change with the seasons?
Neither ACST nor PKT shifts with the seasons, so this 4.5-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

Is PKT ahead of ACST?
PKT is 4 hours 30 minutes behind ACST.
Which time zone does this use?
