GPS Time Error Query

Post by gpslogger »

I'm using Adafruit Ultimate GPS, release version: AXN_2.31_3339_13101700, 5632, PA6H, 1.0.

Once the unit has a fix and a PPS pulse, it reports time 2 seconds (in error) ahead of UTC for a few minutes and then backtracks 2 seconds to match UTC?

How can it be 2 seconds out for so long, considering that accurate time is required to get a fix?

Is this a firmware bug, or normal operation?

Does anyone else experience this behaviour?
