Hello,

I'm trying to understand how the BeagleBone Black synchronize his clock.

I have read the Derek Molloy blog 
(http://derekmolloy.ie/automatically-setting-the-beaglebone-black-time-using-ntp/)
 
but I want to understand the solution provided by the Angstrom distribution.

My BeagleBone clock is correctly set up when I start it with the Wifi USB 
key. It's set up without any specific configuration. For example I don't 
change the /etc/default/ntpdate file so the NTPSERVERS is still empty.
My interpretation of the /usr/bin/ntpdate-sync script is that it exit 
without calling nptdate if the NTPSERVERS is empty:

if [ "$NTPSERVERS" = "" ] ; then
    if [ "$METHOD" = "" -a "$1" != "silent" ] ; then
        echo "Please set NTPSERVERS in /etc/default/ntpdate"
        exit 1
    else
        exit 0
    fi
fi

Does it mean the BeagleBone clock is another way ? or does I'm wrong ?
