Hello<br>
<br>
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>
<br>
I think setting the currenttime can be a good idea on the rbf tool :-)<div class='profimail-signature'><br>Nicolas Repentin<br>

<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? <br>
