Copy pasta

In 2.7.7 / 2.7.8 we introduced some new checks for time accuracy.

In combination, these result in a spamming of the logs when a bad time is found

When the GPS is active, we're calling the GPS thread every 0.2secs.

So this log could be printed 4,500 times in a no-lock scenario :)

Reserve this experience for developers using GPS_DEBUG.
