What time is it in Kuching?

Malaysia spans 2 time zones, so the answer depends on where in it you mean. Kuching covers sabah, sarawak and is on the same clock as Kuala Lumpur, though the two are separate zones in the IANA database and can diverge when daylight saving rules differ.

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