Deployment Guide

○ end-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.
○ end-year: Enter a four-digit number as the year. The range is from 1993 to 2035.
○ end-time: Enter the time in hours:minutes. For the hour variable, use the 24-hour format; example, 17:15 is 5:15 pm.
○ offset: (OPTIONAL) Enter the number of minutes to add during the summer-time period. The range is from 1 to1440.
The default is 60 minutes.
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
changed from
"Summer time starts 00:00:00 Pacific Tue Mar 14 2017 ; Summer time ends 00:00:00 pacific
Tue Nov
7 2017" to "Summer time starts 02:00:00 Pacific Tue Mar 14 2017;Summer time ends
02:00:00 pacific
Tue Nov 7 2017"
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.
