TIME ZONE & DST
There are two ways you can set the time zone on the IP Phones.
Method 1
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"
example:
time zone name: US-Eastern
Method 2
You can use the Time Zone option in the IP Phone UI or your can use the "time zone name"
parameter in the configuration files, and specify a value of "Custom" for this parameter (must
use initial caps). The "Custom" option 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
