â—† The time acquired from time servers is used to record accurate dates
and times for log events. Without SNTP, the switch only records the
time starting from the factory default set at the last bootup (i.e.,
00:00:00, Jan. 1, 2001).
â—† This command enables client time requests to time servers specified via
