I don't think any armv7 board like cubie has a battery to backup
clock<br>
I think ntpd is the only way, and seems to work well on my bpi
with c7. I will check if dns resolution works when date is 1970.<br>

I think setting the currenttime can be a good idea on the rbf tool

On the Fedora-arm list I was pointed to Systemd-timesyncd<br>
<br>
This does MOST of what I want. All that I think needs to be added
is for it to be enabled in the image and a initial date/time of the
image built date be there so the firstboot has a decent time.<br>

I have seen a number of challenges becuase the system time is
back at
<br>
the epoch start as there is no battery rtc. And I wonder how
many
<br>
armv7 boards have a battery to maintain time across boots?
<br>
<br>
Minimally, a process could right the time, in the proper format,
to a
<br>
file, say /etc/currenttime every 5 min and at shutdown.
<br>
<br>
Then date can be run early in the boot process, piping this file
in. It
<br>
would not be perfect and does not help, much for new installs,
but
<br>
better than epoch start.
<br>
<br>
Plus /etc/currenttime can be at least set to the image build
date/time
<br>
so not even firstboot will be at epoch start.
<br>
<br>
Opinions?
