millisecond timer value

[pritam]

What is value that millisecond timer returns? What is the basis for that? Does it depends system clock?

[Pnt]

It just counts ms.

I don't understand what your question is. What are you trying to do ?

Of course it depends from the system clock. Windows have resolution of 1 ms, that is why it has the same resolution

The millisecond timer (tick count) returns a number that has no relation to the actual absolute time of your PC. It can be used to time events, to (approximately) millisecond precision.

If you call the function once, it will return a number like 24516526

if you call it again 300 milliseconds later it will return 24516823  (or there abouts, it could differ by a few milliseconds as Windows is not a deterministic real-time OS).

I think the counter is reset as Windows boots up.
