How do I check for DST?

Can someone please tell me why this doesn't work and how to fix it?

PHP Code:


		
			
 if (!$post['dstonoff']) {
    $post['tzoffset']--;
}else{
   // DST is on, add an hour
$post['tzoffset']++;
}

It seems it wants to grab whatever I am checking for first and not go any further. I always have to change this whenever DST goes off or on. ;)

The wy vB does it is via a test in Javascript at the bottom of the page, and if th etest is true, it runs a cron which updates the user profile (I think?) - it's not by any means a simple thing...

The code above works if you only use one of them. Then it works right. But if you try to "else" them, then it only picks the first one, no matter which one it is. How can I get it to work with "else"?

Is dstonoff a TRUE/FALSE item? the only way that (!$post['dstonoff']) would never return the first (or second) clause is if $post['dstonoff'] is never FALSE (or TRUE)...

All I know for sure is that whichever one I put first always works. How would I check for it then? ;)

try

PHP Code:


		
			
if ($post['dstonoff']===TRUE) 

{   // DST is on, add an hour

    $post['tzoffset']++;

}

else

{

    $post['tzoffset']--;

}

I'll try this and let you know. ;)

Should there be 3 equal signs?

Yeah: it's a more exact test...

All times are GMT. The time now is 11:44 PM.
