Why does double Stopwatch::real() always return a whole integer value? Stopwatch::system() and Stopwatch::user() return fractional second values, as expected. DEC C++ V5.5-004 on Digital UNIX (Alpha) OSF1 V3.2 148 alpha Thanks, Paul [Posted by WWW Notes gateway]

I wish I could give a good reason but I can't. I went back and read the AT&T description (from which our stopwatch evolved) and it doesn't even go into details of the return values, except to say "returned in units of seconds". Real is "wall clock" time and it could be that most wall clocks don't have fractional seconds listed. bjm | |||||

For anyone who may be interested, I have written a stopclock class that does most of what Stopclock does, but with fractional real time (accurate to the clock tick interval, 1/60 sec in my case). I can post a copy here (approx. 200 lines) if anyone wants. Paul [Posted by WWW Notes gateway] | |||||
