Note

Configuring the Time Zone

You can specify a time zone for the switch.
To specify the local time without the daylight saving time feature, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# clock timezone <timezone
name> <-23 to 23 hours offset from UTC time>
<0 to 50 minutes offset from UTC>
Example:
switch(config)# clock timezone PST -8 0
Step 3
switch(config)# exit
switch#
Step 4
switch# show clock
Step 5
switch# show run
Adjusting for Daylight Saving Time or Summer Time
You can configure your switch to adjust for daylight saving time (or summer time). By default, MDS
SAN-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, you can have the switch advance the clock one hour at 2:00 a.m.
on the first Sunday in April and move back the clock one hour at 2:00 a.m. on the last Sunday in October.
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, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# clock timezone
timezone_name hour_offset_from_UTC
minute_offset_from_UTC
Example:
switch(config)# clock timezone PST -8 0
switch(config)# no clock timezone
