3.9. Date and Time
3.9.1. Overview
Correctly setting the date and time is important for NetDefendOS to operate properly. Time
scheduled policies, auto-update of the IDP and Anti-Virus databases, and other product features
such as digital certificates require that the system clock is accurately set.
In addition, log messages are tagged with time-stamps in order to indicate when a specific event
occurred. Not only does this assume a working clock, but also that the clock is correctly
synchronized with other equipment in the network.
Time Synchronization Protocols
NetDefendOS supports the optional use of Time Synchronization Protocols in order to automatically
adjust the local system clock from the response to queries sent over the public Internet to special
external servers which are known as Time Servers.
3.9.2. Setting Date and Time
Current Date and Time
The administrator can set the date and time manually and this is recommended when a new
NetDefendOS installation is started for the first time.
Example 3.25. Setting the Current Date and Time
To adjust the current date and time, follow the steps outlined below:
Command-Line Interface
gw-world:/> time -set YYYY-mm-DD HH:MM:SS
Where YYYY-mm-DD HH:MM:SS is the new date and time. Note that the date order is year, then month and then
day. For example, to set the date and time to 9:25 in the morning on April 27th, 2008 the command would be:
gw-world:/> time -set 2008-04-27 09:25:00
Web Interface

Note: A reconfigure is not required

need to reconfigure or restart the system.
