If there is a "good reason" I'd like to hear it - 500 ppm has the smell of arbitrariness about it. > If you have a computer with a frequency error of more than 500 PPM, > you can either get it fixed or hack the ntpd code to allow +/- 600 or > 6000 or whatever PPM. Of course, one can hack the code. But one should not have to do this to overcome arbitrarily-imposed unjustified constraints. That Chrony can manage much more than 500 ppm may not not be absolutely probative in this regard but it sure is strongly indicative.
