I’m using the Angstrom that came with my Beaglebone Black received today. I’m trying to get ntpdate to run and set the time via the network on boot.
Connman has a ntp client built in:
/usr/lib/connman/test/set-global-timeservers 0.europe.pool.ntp.org 1.europe.pool.ntp.org 2.europe.pool.ntp.org 3.europe.pool.ntp.org
It works with recent connmans.
If ntpd service is running it will automatically update the time on boot so there is no need to resort to ntpdate.
/usr/sbin/ntpd is part of the ntp package.
Regards
Sid.
I have started looking at the Journal information (journalctrl), to help debug why I can not get my wifi to work… And I think the issue with the date is that it is run before the network gets up and bails. I see some time stamps like:
journalctl -b

Then later the network responded and setup eth0… For example finally got an address…

The kludge I am doing, is on my root account, I updated my .bashrc file to add:
ntpdate-sync
Does not work if I wish to create another user and run it from there, but once I logon, this does finally update the date. Hopefully we will come up with a better solution as I would like to put this on a robot and hopefully not have to putty into it to set things up…
