Hal, thanks for reminding me of what I ran into on the LEA-6T modules. When you first power them on, they are often a second off in time. It's not until the NAV-TIMEUTC->valid field returns a set validUTC flag that the time can be counted on. But it usually doesn't take more than a minute or two after power-on that the flag gets set and the time jumps to valid time.

I'm pretty sure that I've seen one GPS unit that was off by a second. I'm pretty sure it didn't get fixed by waiting a while. But I don't remember which type it was so this is just a rumor. I think I was using NMEA mode rather than a vendor specific binary mode. -- These are my opinions.
