ntpq is a good start.  There is at least one other command that can 
reveal interesting/useful information but I can't retrieve it from my 
fading memory at the moment.

Those systems should NOT be going out of sync!!!!!  That they are doing 
so says that something is VERY WRONG somewhere.

Does the problem manifest under all three operating systems??  Do all 
the machines involved run 24x7?  Is the network available 24x7?  What 
are you using for a "master server"?  Where does the "master server " 
get time????
