Parameter –

IP Phone UI Options->Time and Date->Time Zone->Others
Configuration Files aastra.cfg, <model>.cfg, <mac>.cfg
Description Assigns a time zone name to the time server.
The Custom option allows you to customize additional time zone
parameters.
The DP-Dhcp option allows you to enable and disable a DHCP Option 2
value for the phone to use as an offset from Coordinated Universal Time
(UTC). If this parameter is enabled, the phone derives the time and date
from UTC and the time offset offered by the DHCP server.
Notes:
1. Assigning the name “Custom” (with initial cap) in the
configuration files, allows you to create a custom time zone using the
additional parameters in the section
“Custom Time Zone and DST
Settings” on page A-57 .
2. When DHCP Option 2 is enabled on the phone, the phone still
uses the custom timezone configuration settings to control daylight
savings time.
3.
The default behavior for the phone is to use the NTP server from
Option 42 (or current configuration setting) and the current timezone
settings.
