[Boost-users] boost timer with sleep

The following code: #include <iostream> #include #include int main() { boost::timer t; sleep(1); std::cout << t.elapsed() << std::endl; t.restart(); sleep(3); std::cout << t.elapsed() << std::endl; return(0); } Returns (compiled with gcc 4.2.4 on Ubuntu Linux 8.04 using boost 1.36): andre@andre-desktop:~/test$ ./timer_test 0 0 Is this result expected? Why? There is another timer implementation that works with sleep? []'s Andre Paim Lemos
