About GPS Time
GPS time is measured in weeks and seconds since January 6, 1980 00:00:00 UTC. Unlike UTC, GPS time does not include leap seconds, so it is currently ahead of UTC.
Week Rollover: GPS week numbers are transmitted as 10-bit values (0-1023). Every 1024 weeks (~19.6 years), the week number rolls over to 0. Modern receivers handle this, but older ones may have issues.
