Does daylight saving time change the PKT–ACST difference?
The labels PKT and ACST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this PKT to ACST conversion?
We don’t guess. PKT and ACST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Why might the real-world PKT–ACST difference change during the year?
