Kernel.GetTickCount Method 

The GetTickCount function retrieves the number of milliseconds that have elapsed since the system was started. It is limited to the resolution of the system timer. To obtain the system timer resolution, use the GetSystemTimeAdjustment function.

[Visual Basic]
Public Shared Function GetTickCount() As Integer
[C#]
public static int GetTickCount();

Return Value

The return value is the number of milliseconds that have elapsed since the system was started.

Remarks

The elapsed time is stored as a DWORD value. Therefore, the time will wrap around to zero if the system is run continuously for 49.7 days.

If you need a higher resolution timer, use a multimedia timer or a high-resolution timer.

To obtain the time elapsed since the computer was started, retrieve the System Up Time counter in the performance data in the registry key HKEY_PERFORMANCE_DATA. The value returned is an 8-byte value.
