Setting the Date, Time, and Daylight Savings Time
The current date and time is supported on the Cisco SIP IP phone via SNTP and
is displayed on the phone’s LCD. In addition to supporting the current date and
time, daylight savings time (DST) and time zone settings are also supported. DST
can be configured to be obtained via an absolute (for example, starts on April 1
and ends on October 1) or relative (for example, starts the first Sunday in April
and ends on the last day of October) configuration.
We recommend that date and time-related parameters be defined in the
SIPDefault.cnf file.
Before You Begin
When configuring the date, time, time zone, and DST settings, remember the
following:
•
Review the guidelines and restrictions documented in the “Configuration File
Guidelines” section on page 2-6.
•
Determine whether you want to configure absolute DST or relative DST.
•
The SNTP parameters specify how the phone will obtain the current time
from an SNTP server. Review the guidelines in Table 3-2 and Table 3-3
before configuring the SNTP parameters:
Table 3-2 lists the actions that take place when a null value (0.0.0.0) is
specified in the sntp_server parameter.
