Hi all,
I need to mesure time from one moment to another.
Is there are any equivalent of WinAPI QueryPerformanceCounter()?
Needed accuracy is at least 20 ms. I could use QTime::start() and QTime::ellapsed() but this approach gives problems if someone change system time.
Probably I could use some function that returns time from the begining of runing the application. Wich would be good thing. But I cant find any function like this.
So I need robust and accurate time mesurement. Any ideas?
Thanks
