The NTSC clock constant is 3.579545.
The PAL clock constant is 3.546895.
To determine video format (PAL/NTSC) at runtime:
#include <graphics/gfxbase.h>
struct GfxBase *GfxBase;
GfxBase = (struct GfxBase *) OpenLibrary("graphics.library", 0L);
if ( GfxBase == NULL) /* Couldn't open library; clean up and exit. */
if (GfxBase->DisplayFlags & PAL) /* PAL machine. */
else /* NTSC machine. */
