adjfreq() question

[Alan Corey]

Can adjfreq() adjust the frequency of the real time clock that runs when 
the computer is turned off or is it just the clock within the operating 
system?

I just ported chu by William Rossi and I'm wondering if adjfreq might be a 
workaround for not having Linux's Timex.  I've only had it running a 
couple days, just looking at the first plots.  I don't really need super 
accuracy, something like 1/2 second would be good enough.  There's a 
writeup at http://ab1jx.webs.com/toys/chu/index.html
