From: "Ronald F. Guilmette" Date: Fri, 27 Aug 1999 17:01:35 -0700 Message-ID: <9938.935798495@monkeys.com> Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG OK, so maybe this is dumb question, but I need to know. The documentation for gettimeofday(2) says: struct timeval { long tv_sec; /* seconds since Jan. 1, 1970 */ long tv_usec; /* and microseconds */ }; Is that "microsecond" as in 1/1,000,000 seconds? Or is that "microsecond" as in 1/2^20 seconds? There _is_ a slight but significant difference.
