Use the Generate Time Zone for Phone Numbers program to create or update time zone information for all existing phone numbers in the TCA Registry. The time zone information is based on the phone setup by your administrator. See: Defining Time Zones for Phones.

For example, the US phone setup is based on area codes, since the country has multiple time zones. For the 650 or 858 area code, the program would assign the US west coast time zone.
