The time zone and corresponding DST pre-configurations exist in the AutoDST file. If the DST is set to Automatic, the IP
phone obtains the DST configuration from the AutoDST file.
You can customize the AutoDST file if required. The AutoDST file allows you to add or modify time zone and DST set-
tings for your area each year.
