Configuring Operational Features
Time Zone & DST
There are two ways you can set the time zone on the IP Phones.
First Method - You can set a time zone using the Time Zone option in the IP
Phone UI or you can use the “ time zone name” parameter in the configuration
files. Both methods allow you to enter a value from the Time Zone table. The list
of time zone names is provided in the table in Appendix A, the section,
“Time
Zone Name/Time Zone Code Table” on page A-47. The following is an example:
time zone name: US-Eastern
Second Method - You can use the “ time zone name” parameter in the
configuration files, and specify a value of “ custom ” for this parameter. This
method allows you to customize the time zone for your area using additional
configuration parameters. The following is an example using relative time for
EST:
time zone name: custom
The following table identifies the additional parameters you can enter in the
configuration files if you want to customize your time zone.
