BST Checking

I thought I'd share my code for BST checking, as I just got round to fixing it!
It's pretty simple; work out the date ranges for the year, then check if the date is between them.
function isBST($now) {
  $ThisYear = gmdate("Y", $now);
  $MarStartDate = ($ThisYear."-03-25");
  $OctStartDate = ($ThisYear."-10-25");
  $MarEndDate = ($ThisYear."-03-31");
  $OctEndDate = ($ThisYear."-10-31");
  while ($MarStartDate <= $MarEndDate) {
    $day = date("l", strtotime($MarStartDate));
    if ($day == "Sunday") {
      $BSTStartDate = ($MarStartDate);
    }
    $MarStartDate++;
  }
  $BSTStartDate = (date("U", strtotime($BSTStartDate))+(60*60));
  while ($OctStartDate <= $OctEndDate) {
    $day = date("l", strtotime($OctStartDate));
    if ($day == "Sunday") {
      $BSTEndDate = ($OctStartDate);
  }
    $OctStartDate++;
  }
  $BSTEndDate = (date("U", strtotime($BSTEndDate))+(60*60));

    return (($now >= $BSTStartDate) && ($now <= $BSTEndDate));
}
Pass in a time (e.g. from mktime) et voila!

Updates and improvements

Continuing my run of breaking my wrists working on this site, I've added my C++ course notes, a proper rendition of the notes I've taken for CS2A2, and a publications page (currently empty).
I've also made the front page a little more information rich (for Google's benefit really), and removed the rubbish picture (which was breaking up the flow). A few CSS improvements in the mix too.

My Dell's HDD has bitten the dust; won't spin up, and therefore stops the whole IDE channel from working: me-no-booty. I've lost a bit of stuff, but I have a full Windows backup from 3rd October and some mail backups from a little while ago.
It's still annoying.
Come on Dell, reply to me. It's under 3-year next-business-day on-site kiss-my-ass warranty!
