[USRP-users] USRP time with GPSDO

We have 2 N200's with GPSDOs, connected to different Linux computers. We
discovered that their times (the metadata time stamps) differ by 2 or 3

We eventually traced that to differences in the clocks of the two linux
boxes (one was not running ntpd). However, I am still puzzled by the fact
that the USRP time came from the computer's time and not from the GPSDO

Is that behavior (getting the time from the computer even if a GPSDO is
intalled) normal?
