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. Jerry Freedman,Jr ps I am having problems postin so if this is a repeat then I apologize.
