How is system time set? Is ntpdate run after the network is ready? How
long does it retry waiting for the network to be available?
I have seen a number of challenges becuase the system time is bac at the
epoch start as there is no battery rtc. And I wonder how many armv7
boards have a battery to maintain time across boots?
Minimally, a process could right the time, in the proper format, to a
file, say /etc/currenttime every 5 min and at shutdown.
Then date can be run early in the boot process, piping this file in. It
would not be perfect and does not help, much for new installs, but
better than epoch start.
Plus /etc/currenttime can be at least set to the image build date/time
so not even firstboot will be at epoch start.
Where do we stand wrt gpio support and where are there instructions?
Latest discussion on this was on 1/23/15 and for BBB. I want it on
Trying to decide which way to go with control systems. The esp8266 is
very interesting and cheap as an alternative of doing gpio directly on
