how can i get the tim covered in between 2 or more statements?

In windows API you can use GetTickCount() to recieve the amount of milliseconds since windows started. In a DOS environment you could probably use gettime(), but then you get it in the form h:m:s:hs.

Code:

---

Time1 = GetTickCount();
DoSomething();
Time2 = GetTickCount();
TimeDif = Time2 - Time1;

---

(All times are DWORD:s)

in linux?
