Name” on page A-45 .

Standard ISO 3166)” on page A-196 .
CUSTOM TIME ZONE SUPPORT
A User or Administrator can also set a custom time zone on 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.
On the IP Phone UI for 6867i, 6869i, and 6873i IP phones, a User or Administrator can select
Time and Date->Time Zone->Others

Custom
” from the displayed time zone list.
On the IP Phone UI for 6863i and 6865i IP phones, you select

on page A-45 .
Note:
The country name, country code, and time zone name are case sensitive.
Notes:
1.
When DHCP Option 2 is enabled on the phone, the phone still uses the values
configured for
Daylight Savings
to control daylight savings time.
2.
The default behavior for the phone is to use the NTP server from Option 42 (or
current configuration setting) and the current time zone settings.
3.
If the time zone name parameter is set to a value other than Dhcp, then DHCP
Option 2 is disabled.
