Setting the system clock
In addition to SNTP support, the device also allows you to set the system time counter. It starts the
system time and date clock with the time and date you specify. The time counter setting is not
retained across power cycles and is not automatically synchronized with an SNTP server.
NOTE
To synchronize the time counter with your SNTP server time, enter the sntp sync command from the
Privileged EXEC level of the CLI.
NOTE
Unless you identify an SNTP server for the system time and date, you will need to re-enter the time
and date following each reboot.
For more details about SNTP, refer to “Specifying a Simple Network Time Protocol (SNTP) server” on
page 124.
To set the system time and date to 10:15:05 on October 15, 2005, enter the following command.
BigIron RX# clock set 10:15:05 10-15-05
Syntax: [no] clock set <hh:mm:ss> <mm-dd-yy> | <mm-dd-yyyy>
By default, the device does not change the system time for daylight savings time. To enable daylight
savings time, enter the following command.
BigIron RX(config)# clock summer-time
Syntax: clock summer-time
Although SNTP servers typically deliver the time and date in Greenwich Mean Time (GMT), you can
configure the device to adjust the time for any one-hour offset from GMT or for one of the following
U.S. time zones:
• US Pacific (default)
• Alaska
• Aleutian
• Arizona
• Central
• East-Indiana
• Eastern
• Hawaii
• Michigan
• Mountain
• Pacific
• Samoa
The default is US Pacific.
You can now set the system time clock for countries like India that fall in the ½ hour time zone. Only
the following zones have been added:
• GMT + 11:30
