Setting the date and time using the CLI

Use the CLI commands in this topic to set the time zone on your Email Security - Server appliance.

Important
NTP synchronization is set by default and must be disabled before you can manually configure the date and time. For information about disabling NTP, see NTP server configuration.

Prerequisites

Admin access

To set the date and time:

Go to CLI configuration mode:

hostname > enable
hostname # configure terminal

(Optional) Use the clock set <HH>:<MM> <YYYY>/<MM>/<DD> command to specify the time and date. For example, the following command sets the time and date to 2:00 p.m. on July 21, 2014:
```
hostname (config) # clock set 14:00 2014/07/21
```
Use the clock timezone <timezone> command to specify the time zone. For example, both of the following commands set the time zone to Pacific Standard Time:
```
hostname (config) # clock timezone UTC-offset UTC+8
```
```
hostname (config) # clock timezone America North United_States Pacific
```
Note
The time zone is for display purposes and should match other security device settings.
To restore the default time zone:
```
hostname (config) # no clock timezone
```
View the configured time and date settings:
```
hostname (config) # show clock
```
Save your changes.
```
hostname (config) # write memory
```

Examples

Time and date using the North America Central Daylight time zone:

Date:        2014/06/25
Time zone:   America North United_States Central
             (US/Central)

Time zone:    UTC 
              (Etc/UTC)
