NOTE: If you enter <CR> after entering the recurring command parameter, and you have already set a one-time
daylight saving time/date, the system uses that time and date as the recurring setting.
To view the clock summer-time recurring parameters, use the clock summer-time <time> recurring ? command.

Configuring a Custom-defined Period for NTP time
Synchronization
You can configure the system to send an audit log message to a syslog server if the time difference from the NTP server is
greater than a threshold value (offset-threshold). However, time synchronization still occurs. To configure the offset-threshold,
follow this procedure.
Specify the threshold time interval before which the system generates an NTP audit log message if the system time deviates
from the NTP server.
CONFIGURATION mode
ntp offset-threshold threshold-value
The range for threshold-value is from 0 to 999.
