<desc>Returns the time passed since operating system start. Can be used for exact time measurement.</desc>

<remark>As operating system times will vary on different computers, this function will always return 0 in a network game or playback to avoid synchronization errors.</remark>

<text>This function checks the performance of the function "<funclink>Cos</funclink>". To do this, it executes the function 100 times and calculates the time the process took using GetTime().</text>
