Sounds like a firmware bug. I've seen similar off by a second from NMEA units, but mine only last a few seconds. My units have a marginal view of the sky. They occasionally fade out. I've only seen the quirks when they are recovering from a fade out. If you get another one, you might let it run for a while (hour?) and then power cycle the unit so it has to get synchronized again and see if that fixes things. -- These are my opinions, not necessarily my employer's.
