Parameter –	Configuration Files
time zone name	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-Dhcpoption 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:
	• 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-47.
	• When DHCP Option 2 is enabled on the phone, the phone still uses the custom time-
	zone configuration settings to control daylight savings time.
	• The default behavior for the phone is to use the NTP server from Option 42 (or current
	configuration setting) and the current timezone settings.
