The clock command changes are saved across system resets.
Note
You can specify a time zone for the switch. To specify the local time without the daylight saving time
feature, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# clock timezone
timezone hours_offset minutes_offset
Step 3
switch(config)# exit
Step 4
switch# show clock
Step 5
switch# show run
The following example sets the time zone to Pacific Standard Time (PST) and offsets the UTC time by
negative eight hours and 0 minutes:
switch# configure terminal
switch(config)# clock timezone PST -8 0
To disable the local time setting, perform this task:
switch(config)# no clock timezone

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:
