<title>GetTime</title>
<category>System</category>
<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>("TestCos doesn't work in a network game!"));
var start_time = GetTime();
for(var i = 0; i < 100; i++) <funclink>Cos</funclink>(i, 100);
var time = GetTime() - start_time;
<funclink>Log</funclink>("A call to Cos takes %d.%02d ms", 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>
