Port Moresby does not change its clocks
A fixed offset, all year round
Port Moresby stays on Papua New Guinea Time at UTC+10:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Port Moresby from a country that does change clocks. The offset between you and Port Moresby is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.

How Port Moresby's clock got here
Read from the IANA Time Zone Database, the same rules Linux, macOS and Android use
Before any of this, Port Moresby kept local mean time — solar noon by definition — at UTC+9:49, until 1880. Standard time zones were an attempt to replace that with something people could agree on, and the Port Moresby clock still carries the residue of that original figure.
Every date above is a record in the IANA Time Zone Database, not an estimate. The database is maintained by volunteers who track official announcements; if a government changes its rules, these figures change with it.
