Operational Features
For more information about setting the country code, see Appendix A, "Country Codes (from
Standard ISO 3166)" on page A-192.
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 and 6869i IP phones, a User or Administrator can select Time
and Date->Time Zone->Others and choose "Custom" from the displayed time zone list.
On the IP Phone UI for 6863i and 6865i IP phones, you select Preferences->Time and
Date->Time Zone->Others and enter "Custom" for the country code.
