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
• Manual Setup—You can use the phone web user interface to enter the time and date manually. However,
The time that the NTP Server and the SIP Date Header serve is expressed in GMT time. The local time is
obtained by offsetting the GMT according to the time zone of the region.
You can configure the Time Zone parameter with the phone web user interface or through provisioning. This
time can be further offset by the Time Offset (HH/mm) parameter. This parameter must be entered in 24-hour
format and can also be configured from the IP phone screen.
The Time Zone and Time Offset (HH/mm) offset values are not applied to manual time and date setup
Note The time of the log messages and status messages are in UTC time and are not affected by the time zone
setting.

Configure Daylight Saving Time

The phone supports automatic adjustment for daylight saving time.
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.
Note
NTP time takes priority over the time you set using the menu options on the phone
screen. When you manually enter a time, this setting takes effect. On the next
NTP synchronization, the time id is corrected so that the NTP time is displayed.
When you manually enter the phone time, a pop-up is available that alerts you
of this behavior.
the NTP time or SIP Message Date overwrites this value when either is available to the phone. Manual
setup requires that you enter the time in 24-hour format only.
