Hi Tom, First of all thank you very much for your reply. In my system there are two to three cars. All cars are having embedded board. It receive GPS as well as vehicle status data & give it to our application. Our application detects any accident scenarios based on GPS information & other par

It is not clear to me why you are trying to do this. If you are trying to transfer time from the gps system to the other one, just use it as your time server, and use chrony to get time from it. Yes, your system would have large variations. It takes time for the first system to write the data to
