Checking and setting the system clock

The Message Storage Server (MSS) uses the Linux system clock to perform certain time-dependent tasks, such as performing an unattended backup. The Linux system clock can be set manually or it can be synchronized to a Network Time Protocol (NTP) server. If the system clock is set manually, which is the default for a private LAN installation, you should check the time on a monthly basis and whenever a daylight savings time change occurs.

Use the following procedures to set the date and time on the MSS manually or to administer an NTP server to be the source for the system date and time.

To set the date and time manually:

1. On the Administer Linux Date and Time page, select the Manual radio button and check the date and time information.
2. Correct any date and time inaccuracies.

For more information, click any of the fields or Help.

3. Click Save.
4. Verify that the system confirms the date and time change occurred successfully.

If the change occurred successfully, the system logs a message in the Server Events log about the changes. The system does not reset to the new date and time until the system is restarted.

5. Stop and then start the messaging software. See Stopping the messaging software and Starting the messaging software for more information.

To administer an NTP server:

1. On the Administer Linux Date and Time page, select the NTP Time Server radio button.
2. In the NTP Time Server field, enter the Fully qualified Domain Name or IP address of the NTP server.

Note: If the system uses a Windows Domain Controller on the corporate LAN, that server can also be used as the NTP server.

3. Click Add NTP Server.
4. Click Save.
5. Verify that the system confirms the change occurred successfully.

If the change occurred successfully, the system logs a message in the Server Events log about the changes. The system does not reset to the new date and time until the system is restarted.

6. Stop and then start the messaging software. See Stopping the messaging software and Starting the messaging software for more information.

To delete an NTP server:

1. On the Administer Linux Date and Time page, select the NTP server you want to delete.
2. Click Delete NTP Server.
3. Select or administer a different NTP server or set the system time manually.
4. Click Save.
5. Verify that the system confirms the change occurred successfully.

If the change occurred successfully, the system logs a message in the Server Events log about the changes. The system does not reset to the new date and time until the system is restarted.

6. Stop and then start the messaging software. See Stopping the messaging software and Starting the messaging software for more information.

To synchronize the time on the MASs with the time on the MSS, run the time.bat command on all MASs.
