Additional Switch Configuration Chapter 3 Configuring the Switch Send feedback to [email protected] Note The clock command changes are saved across system resets. You can specify a time zone for the switch. To specify the local time without the daylight saving time feature, perform this task: Step 1 Step 2 Step 3 Step 4 Step 5 Command switch# configure terminal switch(config)# clock timezone timezone hours_offset minutes_offset switch(config)# exit switch# show clock switch# show run Purpose Enters configuration mode. Sets the time zone. timezone is the three letter time zone (PST for Pacific Standard), the hours offset from UTC (-8 for the PST offset), and minutes offset (needed for time zones such as Newfoundland Standard (NST) or India Standard (IST)). Returns to EXEC mode. Verifies the time zone configuration. Displays changes made to the time zone configuration along with other configuration information. 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 Disables the time zone adjustment feature. 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.
