How do I allow system time synchronization?

Please follow these steps:

1. Find out what time server your computer uses to update time, usually it is time.windows.com
2. Put this under the allowed sites.
3. Make sure that the time synchronization is enabled on your computer.

After this is done, the system clock should be able to synchronize (update) the time.

If this does not help, launch Surfblocker, click Settingsand make sure that the option Block changes to system time is unchecked.
