    <version>5.1 OC</version>
    <syntax><rtype>int</rtype></syntax>
    <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>
    <examples>
      <example>
        <code>func TestCos()
{
	if(<funclink>IsNetwork</funclink>()) <funclink>return</funclink>(<funclink>Log</funclink>(&quot;TestCos doesn't work in a network game!&quot;));
	var start_time = GetTime();
	for(var i = 0; i &lt; 100; i++) <funclink>Cos</funclink>(i, 100);
	var time = GetTime() - start_time;
	<funclink>Log</funclink>(&quot;A call to Cos takes %d.%02d ms&quot;, time / 100, time % 100);
}</code>
        <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>
