I am using raspberry pi 1 for my project and I recently flashed new os (2.12.3) with my application. On restart over D-Bus I observed that the time going back to some random time in the absence of NTP. I have also observed that I was not able to get few environmental variables. Earlier I was using 2.2.0 and I have never seen such problems before.
Can I know is there any OS specific things that I should take care of for the latest versions
