Adjusting for Daylight Saving Time or Summer Time
You can configure your switch to adjust for daylight saving time (or summer time). By default, Cisco NX-OS
does not automatically adjust for daylight saving time. You must manually configure the switch to adjust to
the daylight saving time.
For example, following U.S. standards (defined by the Energy Policy Act of 2005), you can have the switch
advance the clock one hour at 2:00 a.m. on the second Sunday in March and move back the clock one hour
at 2:00 a.m. on the first Sunday in November. You can also explicitly specify the start and end dates and times
and whether or not the time adjustment recurs every year.
To enable the daylight saving time clock adjustment, perform this task:
