Hi All

Just on this issue, if a location discrepancy can be upto say a kilometre or so and still be fine, what about actual time?

The reason I ask is that I have always sync'ed my laptop to an internet time service using a program Dimension4. I notice that with my GPS units, there is a difference of 90seconds between them and the internet.
Would 90 seconds make that much of a difference? I would have thought that it would, given the drift that can occur in that time.

Also, since the GPS navigation system runs on timed signals, I would expect that the GPS reported time would be more accurate and the one to work off. Is that correct?

Thanks
Darrell
