If you are using glut you can use glutGet(GLUT_ELAPSED_TIME).

Timers have nothing to do with OpenGL (disregarding GLUT, which I know very little about). Look into QueryPerformanceCounter() and QueryPerformanceFrequency() in the Win32 API.

time.h
easier? it might be a couple lines shorter.
as accurate? QueryPerformanceCounter() is much better.

Go with QueryPerformanceCounter(). You get a better timer for almost no extra work.
