Why not
cat /n/gps/time
This prints three numbers, the time in seconds since the epoch,
the GPS time in nanoseconds since the epoch and the local time
in nanoseconds since the epoch (the local time at which the GPS
time was received). The difference between the 2nd and 3rd number
measures how far your local clock is off.
Without running timesync, try to see if the numbers make sense.
