That didn't work - the date on the email is still showing 8 hours behind. Code is below.
$header .= "MIME-Version: 1.0\r \n";
$header .= "Content-Type: text/html; charset=iso-8859-1\r \n";
$header .= "X-Priority: 3\r \n";
$header .= "X-MSMail-Priority: Normal\r \n";
$header .= "X-Mailer: Microsoft Outlook IMO, Build 9.0.6604 (9.0.2911.0)\r \n";
$header .= "Importance: Normal";
$header .= "X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1165";
$header .= "Date: ".date('D, d M Y H:i:s', time()+28800);
$msubject = "Order Confirmed";
$mbody = "Blah Blah";
$mailcustomer = mail($regemail, $msubject, $mbody, $header);
Any clues to whats wrong?
