Preventing employees from changing the system clock.

Post by mikeb »

TimeTrex does its best to account for clock skew or tampering whenever possible, but in some situations, especially offline mode when the server can't be reached and the clock skew is more then one day, there isn't much it can do.

Because of this, we recommend that you enable Internet Time Server clock synchronization and disable the ability to change the clock by using Local Security Policies.

To enable internet time server synchronization:

1. Right click on the clock in the lower right hand corner of the screen.
2. Adjust Date/Time
3. Click the "Internet Time" tab.
4. Check "Automatically synchronize with an Internet time server"
5. Make sure a time sever is selected.
6. Click the "Update Now" button.

To prevent employees from changing the system clock:

1. Go to: Start -> Control Panel -> Administrative Tools -> Local Security Policy
2. Once in Local Security Settings, go to: Local Policies -> User Rights Assignment
3. On the right hand side, double click on "Change the system time"
4. Remove all users or groups from the list, press "OK"
5. Logoff or reboot your computer.
