cookies are 2 minutes off in IE (with setcookie)

[nujai]

???

I've been searching for information about this to no avail.

 

I'm testing pages using cookies set with setcookie.  I suddenly started experiencing failures in IE.

But Firefox was still fine.

 

I noticed that it had to do with the cookie expiry time  (I have v. 7).  I had lowered the expiry threshold so I wouldn't have to keep clearing my browser cookies to test.

 

Is there some kind of minimum expiry time for IE??  Like 2 minutes...?

Does IE shave two minutes off the top?

 

Here's what I found:

 

time() + 3600 gives me 58 minutes in IE and 1 hour in Firefox

time() + 60 gives nothing I have time to notice in IE and a minute in firefox

time() + 120 gives me a couple seconds in IE and 2 min in firefox

 

Is this an IE "feature" or is it me that's doing something wrong?  I am new to this after all...

 

example of how i set the cookies:

$hour = time() + 120;

setcookie(wpsite, $_POST['username'], $hour);

 

does work for the most part, just that little issue so far....

 

If anyone knows about this, pls let me know.  I don't care whether it's fixable or not, it's just that I though I was going crazy at first when I was trying to troubleshoot the problem; could not figure out what was going on initially.

 

Thanks.
