i'm hoping your tool can fix this... and will work with the gps...

If you have root access, this app can set the system time to the GPS time. Not 100% sure this will stop the system from still using the inbuilt GPS time though.

i have root access, the problem is that the time from gps is incorrect due to that bug and 1024 weeks need to be added, see java code example

I saw, but is this specific app causing this? If not, I think this app will not have the same issues as described

NH-Networks commented 3 years ago

No it's not app related, that app needs a fix also in code but i have no idea how... changes are needed in decompiled smali files i guess...

But time sync can be turned off in settings so that app will no overrule it... now i only need a other app that runs as a service that prevent time and date to fall back to "today date - 1024 weeks"

Ah, tbh I've just had a look at my code and I don't even parse the "date" only the UTC time, so I don't think there is anything I can fix here.
