Re: Setting remote node System Time/Clock?
If you have ntp servers available (even just using the one board with
the clock chip) you can use ntpdate to set the initial time. Otherwise
you have to roll your own. (Popular approaches include rdate,
time/daytime, active or passive ssh script, etc.)

I may be missing something, but doesn't "rtc [-s] net <node>" do what you require?
