On my eagle explorer, when the real utc time is say 12:00:00, my receiver
shows 11:58:58, a two second difference.
You need to get a receiver such as the garmin GPS25 LP because it designed
for accurate time output.  Handheld receivers are not designed for accurate
time output.
The gps satellite trasmit very accurate time, it is your receiver that
makes the difference.
