Thanks everybody for your answers,

I found easy to synchronize the PC clock with this method, You are right
Hermann, even without a storage scope, by noticing the min/max boundary, you can
see the drifting along scope screen. The clock is adjusted in an hour or two by
this way. After that, just have to adjust the offset at power up.

BTW, I know there is a project under sourceforge.net for a GUI with Linux but it
seems to be at the very first beginning. One can benefit of NTP protocol to have
a precise system clock in this case.
