Well, I've managed to emulate exactly what the PHP developer was doing, which means it's a bit hacky:

            Dim intEvent As Integer = CInt(strCurrentEvent.Substring(0, 3))
            Dim intTime0 As Integer = CInt(strCurrentEvent.Substring(3, 3))
            Dim intTime1 As Integer = CInt(strCurrentEvent.Substring(6, 3))
            Dim intTime2 As Integer = CInt(strCurrentEvent.Substring(9, 3))
            Dim intTime3 As Integer = CInt(strCurrentEvent.Substring(12, 3))
            Dim datDate As DateTime = New Date(1970, 1, 1, 1, 0, 0).AddSeconds(CInt("&H" & String.Format("{0:x4}", (intTime3 &lt;< 8) Or intTime2) & String.Format("{0:x4}", (intTime1 << 8) Or intTime0)))

(With extra date offset to convert the time to GMT)

Can anyone think of a less "hacky" way to do this?

Hi all,
Can someone give me a hand converting this PHP code to VB.NET? I'm completely bamboozled by it all! Basically there is a large string which stores some event data and a timestamp. The timestamp is split into 4 strings, which are converted to an unsigned integer (to make the timestamp) and then converted to a string representation of the date.

$eventline = "008100146055074000000000028025045070000002020005";
$n = sscanf($eventline, '%3u%3u%3u%3u%3u', $event, $time0, $time1, $time2, $time3);
$time = sprintf('%04X', ($time3<<8)|$time2) . sprintf('%04X', ($time1<<8)|$time0);
$timestamp = date('Y-m-d H:i:s', intval($time, 16));
echo($timestamp);

(Returns: 2009-06-16 07:39:00)
