I need to adjust the ESX server time zone from PST (GMT -8) to Arizona (GMT -7). Arizona does not use Day-Time-Saving (DST)

From the VMware KB, I need to:
- Edit the file to show the relative path to the file representing the new time zone, and ensure that UTC and ARC are set as shown:
ZONE="US/Pacific"
UTC=false
ARC=false

For, ZONE="US/Pacific" --> Do I need to change this to "US/Arizona"?

Alos, is ZONE="America/Pacific" is the same as ZONE="US/Pacific"

Thanks
