Yes, I have some patches to make ntpd run under IRIX.  I hacked up ntpd on
the on our iri to accept the "tickadj" var, multiply by 1000 and use it to
set timetrim via the syssgi() function and SGI_SETTIMETRIM (there is also a
SGI_GETTIMETRIM). Tickadj is in uS/S, timetrim is in nS/S.  I've been using
a value of about -400000 nS/S (so tickadj = -400) for our 4D/20's and a 25:
the logical clock stays synced with that.  timetrim is a signed long.

Check babar.mmwb.ucsf.edu [128.218.21.42] in ~ftp/pub/ntpd.patch for the
patch and the Makefile.
