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:
