Can't create time_duration with milliseconds on VS.NET 2003
I am using VS.NET 2003 and attempting to create a time_duration using hours, minutes, seconds, and milliseconds. However, I get an error message regarding the 4th parameter (milliseconds). Here is my code and the error message:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // main.cpp
#include "boost/date_time/posix_time/posix_time.hpp" using namespace boost::posix_time; void main() { time_duration t(8, 45, 00, milliseconds(100)); }

The error is valid. Milliseconds is-a time-duration so you don't pass it as the fourth parameter. Add it instead. Something like: Try this instead: time_duration t(8, 45,0); t += milliseconds(100); or even clearer: time_duration t = hours(8) + minutes(45) + milliseconds(100); Jeff
