Configuring Date, Time, and Time Zone Chapter 5 Initial Configuration Send documentation comments to [email protected] Where HH represents hours in military format (15 for 3 p.m.), MM is minutes (58), SS is seconds (09), DD is the date (23), Month is the month in words (September), and YYYY is the year (2002). Note The date and time changes are saved across system resets. 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: Step 1 Step 2 Step 3 Step 4 Step 5 Command Purpose switch# config t Enters configuration mode. 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 Sets the time zone with a specified name, specified hours, and specified minutes. This example sets the time zone to Pacific Standard Time (PST) and offsets the UTC time by negative eight hours and 0 minutes. switch(config)# exit switch# Returns to EXEC mode. switch# show clock Verifies the time zone configuration. switch# show run Displays changes made to the time zone configuration along with other configuration information. 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 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, 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: Step 1 Step 2 Command switch# config t switch(config)# 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 Purpose Enters configuration mode. Offsets the time zone as specified. This example sets the U.S. Pacific standard offset time as negative 8 hours and 0 minutes. Disables the time zone adjustment feature. 5-18 Cisco MDS 9000 Family CLI Configuration Guide OL-18084-01, Cisco MDS NX-OS Release 4.x
