The GPS calculates the time after it calculates position so the time may be
delayed by many seconds and the GPS leap second count may be off if it
isn't updated.

4 second error ~ 1 mile error.

So, if the time isn't correct on the GPS, why is the position it calculates
correct?

A mile off in the middle of the ocean doesn't sound like much of a
problem! I would think a bigger issue is that you would want to
practice with a traditional clock.
