Chamorro Standard Time Zone - CHST

Chamorro Standard Time is ten hours ahead of Coordinated Universal Time standard, written as an offset of UTC + 10:00. That means to find the standard time in the zone you must add ten hours to Coordinated Universal Time.

Territories observing the time zone are primarily in the Pacific. It runs through Guam and the Northern Mariana Islands. In Guam, they refer to this time zone as Guam Standard Time or GST.

Both of these areas observe Chamorro Standard Time or ChST all year long, and they do not observe Daylight Saving.
