[amibroker] How to express "after 10 seconds of event X" ?

[huanyanlu]

Hi

I want to know how to express the idea of "after 10 seconds of event 
X" in AFL. I know you can do it by using getperformancecounter(). But 
is there a more simple way of doing this ?

I want to do it with timenum() and now(4) as follows, but 
timenum() has limitation for this, as you can see 

10 seconds after 10:00:56 is 10:01:06 
but timenum() for 10:00:56 is 100056 and timenum() for 10:01:06 is 
100106,  100106-100056=50 , not 10.

thanks for any help / Huanyan

if( event X )
   
   {

        timezero = LastValue(TimeNum());
   }
                
  
elapsedtime = Now(4)-timezero;

10secons_after_X= elapsedtime==10;
