After proper configuration, the following log will be printed on the CLI interface:
*Sep 9 11:31:29: %SYS-6-CLOCKUPDATE: System clock has been updated to
11:31:29 UTC Wed Sep 9 2009.
The above log indicates that the clock of SwitchB (NTP client) has been
updated.

SwitchB#show ntp status
Clock is synchronized, stratum 13, reference is 1.1.1.1
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**24
reference time is CE5212A1.E5D712A0 (11:40:17.000 UTC Wed, Sep 9, 2009)
clock offset is -0.00005 sec, root delay is 0.00000 sec
root dispersion is 0.00002 msec, peer dispersion is 0.00002 msec
The above information shows that the NTP client has successfully connected to
the server and the time of Switch B has been synchronized with the time of
Switch A, with stratum level being higher than that of Switch A by 1 level (i.e.,
13).
