Cannot Set ExpireTime in a cookie

This is a follow-up to my previous cookie post. I discovered that the bit that Internet Explorer 4.0 didn't recognize a cookie as valid when I included an expiration time. This Works: setcookie ("ArtPrintSession",$SessionID); This Doesn't Work: setcookie ("ArtPrintSession",$SessionID,time()+3600); I also tried setting the expiration time earlier in a script and assigning it to a variable: $ExpTime = time()+3600 setcookie ("ArtPrintSession",$SessionID,$ExpTime); That also didn't work. The $ExpTime values look like: 997317780 What's the bug??? Thanks, Jeff Gannaway
