Time Commands
The system clock can be dynamically set by polling a set of specified time servers
(NTP or SNTP). Maintaining an accurate time on the switch enables the system log
to record meaningful dates and times for event entries. If the clock is not set, the
switch will only record the time from the factory default set at the last bootup.
