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.

Dell EMC Networking OS Time and Date
You can set the time and date using the Dell EMC Networking OS CLI.
Configuration Task List
The following is a configuration task list for configuring the time and date settings.
● Setting the Time and Date for the Switch Software Clock
● Setting the Timezone
● Setting Daylight Saving Time Once
● Setting Recurring Daylight Saving Time
Setting the Time and Date for the Switch Software Clock
You can change the order of the month and day parameters to enter the time and date as time day month year. You cannot
delete the software clock.
The software clock runs only when the software is up. The clock restarts, based on the hardware clock, when the switch
reboots.
To set the software clock, use the following command.
● Set the system software clock to the current time and date.
EXEC Privilege mode
clock set time month day year
○ time: enter the time in hours:minutes:seconds. For the hour variable, use the 24-hour format; for example, 17:15:00 is
5:15 pm.
○ month: enter the name of one of the 12 months in English. You can enter the name of a day to change the order of the
display to time day month year.
○ day: enter the number of the day. The range is from 1 to 31. You can enter the name of a month to change the order of
the display to time day month year.
○ year: enter a four-digit number as the year. The range is from 1993 to 2035.
