Wrong time

I often see that my workouts are recorded with a different time than the workouts of friends with whom I was on a ride. The differences reach 2-3 minutes. I noticed that the time in the Karoo is different (2-3 minutes) than the actual time.  Karoo 3 syncs time only when it has access to WiFi, syncing time from GPS or BT-connected cell phone does not work.

My Karoo rarely connects to WiFi, this is the reason why the time problem occurs.

In addition, I think that due to the fact that the Karoo has a different time than the real one - the GPS Fix is reached much later than in the Karoo 2.
