The getitimer(2) man page says the resolution of the system clock is rounded to 10 microseconds; however, the timevals we get back from getitimer() and gettimeofday() have the .tv_usec field rounded to 10 MILLIseconds. We haven't been able to locate this rounding action in the source. Does any one know what's going on here? Tim Davis LHNCBC/National Library of Medicine (301) 496-1936 tim@nlm-vax ARPA
