What time is it in Coyhaique?

Chile spans 4 time zones, so the answer depends on where in it you mean. Coyhaique covers aysen region and is on the same clock as Santiago, though the two are separate zones in the IANA database and can diverge when daylight saving rules differ.

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