GetTickCount return value

Keywords: GetTickCount clock count seconds

---

GetTickCount does not return the actual number of hardware ticks that occurred. It returns the number of "Virtual" clock ticks that have occurred since Windows was started.

For normal Windows, each virtual clock tick is about a millisecond ( 1/1000 of a second). There are times when the tick count may be suspended, such as when running a DOS Box full screen.
