synchronization server, or if you do not wish to use one, you can choose to manually set the date and time.
To manually set the date and time:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the admin
interface .
2. Login as admin.
3. Select the Date and Time link in the Configuration menu; the date and time configuration page
opens.
4. Type the desired date in the Date field. Use the format yyyy-mm-dd.
