Jeremy Cooper opened issue #6: Deliver timestamps in UTC instead of GPS time at NLighten Systems / Kompressor Firmware

Summary

After testing the latest firmware, I noticed that the fine timestamps produced by Kompressor are a good 18 seconds later than that reported by a RAK5146 and the local host time. I now know that this is due to the difference between UTC and GPS time (currently 18 seconds) due to UTC tracking "leap seconds" at the direction of the IERS. This is an area of potential confusion and worth fixing.

The difference between GPS and UTC time is supposedly broadcast in the GPS stream and should be accessible somehow in the ZOE-M8Q.
