Wrong time in iGO Nextgen

[rider]

Hi.
Since a few days suddenly the time ( in top right button ) is one hour later on my tablet.
After app launch the time is ok for say 10 / 20 sec but it looks like when it finds the gps fix, time jumps one hour later while Android time is correct.

I started GPS UP app and I see this :

15-07-2001 ?

In iGO settings > GPS info also shows the wrong GPS UTC time ( or not available ) and no GLONASS at all, outside under a clear sky :

GPS UP on my smartphone Android 10 ( next to the tablet ) :

So, that is ok.

No Android and app updates installed, automatic updates always disabled although sometimes when starting the tablet I see the little download arrow on top downloawding something ?
Maybe Google screwed up something again ? Had that a few times in the past after such a invisible update of something, no idea what.
But did not noticed that the last few days.

Does iGO Nextgen use GPS time or Android system time ?

Wrong time is not such a big problem but when I calculate a route of let's say 10 min after calculation that route will take 80 minutes.

What's happening ?
Is there a setting in sys.txt to use the system time maybe ?

I noticed the same problem a few days ago in my car Head Unit ( Android 6.0.1 - same iGO version ) yesterday but I checked today a few times
but everything seems to be fine suddenly.
