Time Zones
Cisco UCS requires an instance-specific time zone setting and an NTP server to ensure the correct time display in Cisco UCS Manager. If you do not configure both of these settings in a Cisco UCS instance, the time does not display correctly.
Setting the Time Zone
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | UCS-A# scope system | Enters system mode. |
| Step 2 | UCS-A /system # scope services | Enters system services mode. |
| Step 3 | UCS-A /system/services # set timezone | At this point, you are prompted to enter a number corresponding to your continent, country, and time zone region. Enter the appropriate information at each prompt. When you have finished specifying the location information, you are prompted to confirm that the correct time zone information is being set. Enter 1 (yes) to confirm, or 2 (no) to cancel the operation. |
| Step 4 | UCS-A /system/services # commit-buffer | Commits the transaction to the system configuration. |
| Step 5 | UCS-A /system/services # exit | Enters system mode. |
| Step 6 | UCS-A /system/services # exit | Enters EXEC mode. |
| Step 7 | UCS-A /system/services # show timezone | Displays the configured timezone. |
The following example configures the timezone to the Pacific time zone region, commits the transaction, and displays the configured timezone:
UCS-A# scope system
UCS-A /system # scope services
UCS-A /system/services # set timezone
Please identify a location so that time zone rules can be set correctly.

Configuring an NTP Server
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | UCS-A# scope system | Enters system mode. |
| Step 2 | UCS-A /system # scope services | Enters system services mode. |
| Step 3 | UCS-A /system/services # create ntp-server {hostname | ip-addr} | Configures the system to use the NTP server with the specified hostname or IP address. |
| Step 4 | UCS-A /system/services # commit-buffer | Commits the transaction to the system configuration. |
The following example configures an NTP server with the IP address 192.168.200.101 and commits the transaction:
UCS-A# scope system UCS-A /system # scope services UCS-A /system/services # create ntp-server 192.168.200.101 UCS-A /system/services* # commit-buffer UCS-A /system/services #
Deleting an NTP Server
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | UCS-A# scope system | Enters system mode. |
| Step 2 | UCS-A /system # scope services | Enters system services mode. |
| Step 3 | UCS-A /system/services # delete ntp-server {hostname | ip-addr} | Deletes the NTP server with the specified IP address. |
The following example deletes the NTP server with the IP address 192.168.200.101 and commits the transaction:
UCS-A# scope system UCS-A /system # scope services UCS-A /system/services # delete ntp-server 192.168.200.101 UCS-A /system/services* # commit-buffer UCS-A /system/services #
Setting the System Clock Manually
| Command or Action | Purpose | |
|---|---|---|
| Step 1 | UCS-A# scope system | Enters system mode. |
| Step 2 | UCS-A /system # scope services | Enters system services mode. |
| Step 3 | UCS-A /system/services # set clock mon date year hour min sec | Configures the system clock. |
| Step 4 | UCS-A /system/services # commit-buffer | Commits the transaction to the system configuration. |
The following example configures the system clock and commits the transaction:
UCS-A# scope system UCS-A /system # scope services UCS-A /system/services # set clock apr 14 2010 15 27 00 UCS-A /system/services* # commit-buffer UCS-A /system/services #
