This function returns amount of time that your system has been running in milliseconds. By comparing two values of getTickCount, you can determine how much time has passed (in milliseconds) between two events. This could be used to determine how efficient your code is, or to time how long a player takes to complete a task.

Syntax

int getTickCount ()

Returns

Returns an integer containing the number of milliseconds since the system the server is running on started. This has the potential to wrap-around.

Example

This will start a timer displayed at the top of the screen displayed every frame. You can log any specific moment in time by outputting the currentCount variable. 

screenX,screenY = guiGetScreenSize()
function startTheClock ()
	
	if not systemUpTime then
            systemUpTime = getTickCount () --Store the system tick count, this will be 0 for us
	end
	
	currentCount = getTickCount ()
	
	dxDrawRectangle (screenX *.40, screenY * .09, 250, 50, tocolor(0,0,0,150))
	dxDrawText ( currentCount - systemUpTime, screenX * .48, screenY * .1, screenX, screenY, tocolor(255,255,255), 2)
end
addEventHandler ( "onClientRender", root, startTheClock )
