Perhaps your thread has been preempted during execution causing the delay.

Subject: [Boost-users]  [timer] eclapsed return zero

Hello, I have used the timer class in my application. It works ok sometime but i think it dont work correctly.
 my code is:
 #include <iostream>
 #include "boost/timer.hpp"
 using namespace std;
 using namespace boost;
 int main()
 {
    int count=0;
    timer t;
    for(;count<1000000;++count);
    cout<<t.elapsed();
    return 0;
 }
 and the output:
 0.015
 execute time :0.062s
 
 sometime the output is:
 0
 execute time :0.015s
 
 regards
 hechao
