It's explained pretty well in the man page for adjtimex. I've managed to get my clock almost exactly on time - 1 or 2 seconds a week. I followed the instructions in the man page, though without trying to calculate it in detail; just using trial and error. First you set the -t value to get it approximately right, and then fine-tune it with -f. (I'm sure one could do it more elegantly, but this does work.) One important thing: in Debian, you make the settings in /etc/default/adjtimex and then do /etc/init.d/adjtimex restart.
