The Simple Network Time Protocol (SNTP) enables you to synchronize the
computer system clocks on the Internet to that of a designated SNTP server. SNTP
is a simplified, client-only version of the Network Time Protocol (NTP) that
enables the CSS time-of-day to be synchronized with any SNTP server. Use the
sntp command to configure SNTP on the CSS.
Accurate time-of-day is provided by synchronizing to the UTC time, which
provides time within 100 milliseconds of the accurate time. You can configure
information about the local time zone so the time appears correctly relative to the
local time zone. The CSS can receive the time from only a single SNTP server (in
unicast mode), but the CSS cannot be used to provide time services to other
devices.
Before you synchronize the CSS with an SNTP server, make sure you configure
the proper time zone for the CSS (for example, to EST). Also make sure the time
difference between the CSS internal clock and the SNTP server clock is less than
24 hours. Otherwise, the CSS will not synchronize its clock with the SNTP server.
To configure the time on the CSS, see the
Zone" section for details.
For detailed information on configuring the SNTP server, consult the
documentation provided with the server.
