PBP Displayed Clock-Calendar Drops Hour Setting On Reboot. - jcj52436999 - 12-18-2019
PBP Displayed Clock-Calendar Drops Hour Setting On Reboot or shutdown. Clock appears to hold minutes correctly, but not hour of the day. Almost acts like the PBP fails to hold Time Zone setting across reboots, one must reset the time each time one reboots. Does PBP have a battery held time chip? My PBP was just delivered to me early this month, December; and was delivered with the Debian OS.

I think you might be seeing the same disconnect between the RTC and the kernel, as outlined here. After rebooting and establishing network connection, does your clock set the tie correctly?

The PBP contains an RTC in the RK808 chip, and is shown in the schematics:

Just to confirm, this problem occurs with default Debian OS shipped with the PBP? I am still using the default Debian OS and the behavior you describe is abnormal.

OP may still be using the default Debian OS, and if so the behavior described is abnormal.

That's a good point! OP, do you mind sharing with us what OS you're using? Not all PBP image options are equal.

Sorry, forgot to add that I am using the UPdated default delivered PBP Debian OS and setup, I have run the MrFixit and Debian updates. And each time I start the PBP, it connects rapidly to my internet wifi, but the time hours setting is never correct and will Not hold my corrections settings through a reboot.

Could you possibly be behind a firewall that is blocking NTP requests?

Time is correctly maintained on my Ubu and Mac and Windows laptops, so my Xfinity appears to be connecting OK to web and time

Do the contents of /etc/adjtime on your system look the same as this?:
Code:
0.0 0 0.0

Reading hardware clock from RK808 should work on the Debian images with BSP kernel, on the Manjaro image with mainline, hwclock currently can't read the time from the RK808, there is a bug somewhere...

Firewall None. I've tried behind multiple routers, and my other devices sync appropriately.
I've also run MrFixIt's update script.
Thoughts?
