The following example shows the clock summer-time recurring command.
DellEMC(conf)#clock summer-time pacific recurring Mar 14 2009 00:00 Nov 7 2009 00:00 ?
DellEMC(conf)#02:02:13: %RPM0-P:CP %CLOCK-6-TIME CHANGE: Summertime configuration
changed from
"none" to "Summer time starts 00:00:00 Pacific Sat Mar 14 2009;Summer time ends 00:00:00
pacific
Sat Nov 7 2009"
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.
The following example shows the clock summer-time recurring parameters.
DellEMC(conf)#clock summer-time pacific recurring ?
<1-4> Week number to start
first Week number to start
last Week number to start
<cr>
DellEMC(conf)#clock summer-time pacific recurring
DellEMC(conf)#02:10:57: %RPM0-P:CP %CLOCK-6-TIME CHANGE: Summertime configuration

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.
