Clock from 30003 and 7879 port
« on: September 25, 2009, 03:42:08 PM »
I have seen a big différence between many Radarbox for my project about the clock timer.
The data export file was synchronize with the local time from the PC, and if this last was wrong all data can't not be synchronize correctly ?

So is it possible to grab  in the ADS-B Frame the good clock or time ?

ADS-B frames don't contain a timestamp.

The mode-s data is decoded in the PC, so the radarbox is just shipping bits to the PC.  The data becomes a target inside the PC, so all you have to do is install an NTP time service and you are good to go.
