Hmm... interesting. I should try to look at the scripts and decipher it sometime.
I didn't use Derek Molloy's techniques, but I've been using the one liner connman http://exadler.blogspot.ca/2013/11/setting-correct-datetime-on-beaglebone.html Which works wheneven connman detects a network connection (basically it is effectively run on an ifup on an interface). This seems to work reliably on Angstrom builds.
