Modifying Time Zones
You rarely modify a time zone’s regional settings. However, you might want to modify other time zone settings such as the display name or daylight savings rules, because these settings occasionally change.
To modify time zone settings
Navigate to the Administration - Data screen, then the Time Zone Administration view.
In the Time Zone list, select the time zone record you want to modify.
Modify the fields as necessary.
In the Detail list, add or modify the records as necessary.
