Solaris implements gethrtime(get high resolution time) that returns a 64-bit value in nanoseconds since some arbitrary time. Its features are: - simpler and faster - higher resolution - no sec/usec conversion required - no clock adjustment (no time warp) hrtime seems to be an attractive alternative since microtime() is used mostly to measure time delta, and easily implemented by extracting part of microtime(). How about implementing gethrtime in FreeBSD? --kj --- Kenjiro Cho Sony Computer Science Laboratory Inc.
