When sleep is "active" your process does not use any CPU time, therefore it will not increase elapsed time. Try instead std::clock() or boost::xtime and compare start and end time if you want real time used.

Yes, sleep is in seconds. I can confirm that through direct experimentation :)

Another forum helped and suggested I use gettimeofday. This works great, but doesn't shed any light on the zeros provided by boost::timer!

Hi,

boost::timer::elapsed() return a time in second. If you wait only 10 ms second you'll not see anything. Try with sleep(10000)...

Cheers ~Benoît

Isn't posix sleep a wait in seconds? usleep is sometimes available as the microseconds function I believe.
