I have a Sun Sparcstation running SunOs 4.0.3. I need to
be able to produce timestamps with 1 millisecond granularity.
Getitimer and setitimer don't cut it. The best I can manage with
them is about 10 millisecond granularity. I need some
advice.

Their scheduling resolution is still 10 ms, though. -- In-Real-Life: Chris Torek, Lawrence Berkeley Lab CSE/EE (+1 415 486 5427) Berkeley, CA Domain: torek@ee.lbl.gov

But unfortunately, only for the 4/60 and 4/330. (I remember hacking up a binary patch to make it work with a 4/65.) By 4.1.1, the code was fixed to check for any Sun4c as well as the two Sun4's which have it (the 4/330 and 4/470). Craig
