# Time Zones

The Mountain Time Zone is 1 hour ahead of the Pacific Time Zone.

The Central Time Zone is 1 hour ahead of the Mountain Time Zone.

The Eastern Time Zone is 1 hour ahead of the Central Time Zone.

Greenwich Mean Time (GMT) is 8 hours ahead of the Pacific Time Zone.

**For example:** Suppose it is 2:57 P.M. in the Central Time Zone.

Then, in the Pacific Time Zone, it will be 2 hours before 2:57 P.M.

Now, 2 hours before 2:57 P.M. is 12:57 P.M.

So, it is **12:57 P.M.** in the Pacific Time Zone.
