Client time/date synchronisation
Many of our clients have set the wrong time/date in the bios mostly as a result of issues with old cmos batteries.
When the server is connected to the internet the time/date is automatically corrected and things work just fine. However, most of the time internet access is off. Then these clients have the wrong time/date and consequently issues with certificate warnings when using the browsers.
Is there another way to synchronize the time e.g. with the server instead of the internet?
