What time is it in Pontianak?

Indonesia spans 4 time zones, so the answer depends on where in it you mean. Pontianak covers borneo (west, central) and is on the same clock as Jakarta, though the two are separate zones in the IANA database and can diverge when daylight saving rules differ.

Pontianak does not observe daylight saving, so its offset from UTC never moves. Its relationship to places that do change shifts twice a year instead.
