The subject of your mail is mentioning the R3000 which doesn't have any kind of timer in the processor. As already mentioned in my other posting do_gettimeofday() is the portable timer interface providing the highest accuracy. But the R3000 processor itself doesn't provide any timers so the precission of the clock will actually depend of the whatever timers are provided by the rest of the system. Hoever I doubt you're actually using a true R3000 - the R3000 is an ~ 1988 vintage processor. Later R3000 processors frequently contain a suitable timer. Ralf
