Flight time - speed differences

1)I would like to have also Flight Time indicated but in Jeti Studio is NOT a parameter. The only position where flight time appears is at the end of the reproduction bar ( top right of the screen) Is it possible to get this parameter on Values table?
Flight time is clearly stated using Data Explorer as you can see on my photo.

2) I migrated from DataExplorer to Jeti because GPS Speed value are correct and same as on my Jeti DS16 data screen.
In Dataexplorer speed is normally 1 m/sec less.
I keep all flight logs for further analysis and I register max value for each model within a season ( max hohe, max speed, max entfernung and so on). In Jeti Studio speed 49,1 in Data Exp 48,1 m/sec

Or I find the way to have flight time stated in Jeti Studio or tell me why Gps speed in Data explorer is not correct: software read a telemetry value, so why it's different?? software doesn't convert from m/sec to Kmh so where is the bug ?

Thanks

This is the solution to get flight time in Jeti Studio.
Atsonished that DataExplorer shows different speed values....... a mystery ?
