Hello,
As I didn't receive the answers I was looking for, here is my last proposal.

Because of the long discussion about QueryPerformanceCounter that didn't came to a real conclusion, I decided to implement two additionnal timers:
- boost::qpc_timer, which use QueryPerformanceCounter() for its resolution. - boost::tgt_timer, which use timeGetTime() for its resolution.
As using those timers would make no sense on another platform than windows, those are not defined by default. One must #define BOOST_QPC_TIMER to get boost::qpc_timer and must #define BOOST_TGT_TIMER to get boost::tgt_timer.
I've always found it really awkward having to define global macros to get features. Why not simply: (in "main" timer include file) ------- #if defined (BOOST_WINDOWS) # include <boost/.../qpc_timer.hpp> # include <boost/.../tgt_timer.hpp> #endif ------- and/or (in specific implementations - qpc/time_get_time_timer) ------- #if defined (BOOST_WINDOWS) namespace boost { class <windows_specific_timer> { ... }; } #endif // BOOST_WINDOWS ------- // Johan
