Time and Date Settings
The Cisco IP Phone obtains the time settings in one of three ways:
• NTP Server—When the phone boots up, it tries to contact the first Network Time Protocol (NTP) server
to get the time. The phone periodically synchronizes its time with the NTP server. The synchronization
period is fixed at 1 hour. Between updates, the phone tracks time with its internal clock.
