Ok will do so with the next version that should come very soon.
I think this code is both inefficient and likely non-portable.
Hum, by definition QueryPerformanceCounter is non-portable ?

Hum you are probably right, I'm not that much used to date_time so I thought
I had to construct using the constructor but what you just showed is indeed
much simpler.
Thank you
