yes difftime() is what I needed, but it's in second too.
I tried some stuff with the number of ticks from the clock (function clock
() : 91 ticks=1 second), it gives good result.
Doing arithmetic with the clock_t type is certainly not very elegant, but
it works in my case ( there isn't a function like diffclock() ). 

btw, thanks for your help !
