For some reason my nano neo would boot and always show the year 2016... The time was also wrong and the date. The hardware clock would show a different time and date from the system clock. The hardware showed the year 1977.
To fix these problems, as I also run a pi-hole server, I did this:
nano /etc/rc.local
Then I add these 6 lines after the nanohat script starts...
/usr/local/bin/pihole restart
/usr/bin/timedatectl set-ntp TRUE
/usr/sbin/service ntp stop
/usr/sbin/ntpd -gq
/usr/sbin/service ntp start
/sbin/hwclock --systohc
Now when I restart the unit, it automatically gets the right date and time, and the pihole dns server begins working again too.
