DHCP Time Offset (Option 2) Support

DHCP Option 42 enables the phone to be configured with the Network Time Protocol
(NTP) server addresses. However, NTP provides the Coordinated Universal Time (UTC)
time so the phone requires the offset from UTC in order to deliver the correct local
time.
Previously, the phones set the offset of UTC from the current timezone setting on the
phone. In Release 2.6, an Administrator can now set the offset of UTC using DHCP
Option 2.
Using the configuration files, an Administrator can use configuration parameter "time
zone name" to enable DHCP Option 2. If this parameter contains the DP-Dhcp value,
the phone derives the time and date from UTC and the time offset offered by the
DHCP server.
Using the IP Phone UI, you can enable the phone to use DHCP Option 2 by setting the
following values from the Country Code list on the phone:
