date problems

[rDubya <ryan.dubya@xxxxxxxxx>]

I'm having a problem with dates in php and mysql.  I run a site that
promotes dated events and concerts and has the information for each
stored in a mysql database with the timestamp field.

Here is the function that checks the date of the event to ensure it is
between now and three weeks from now (only events in this time period
are displayed on a page, with all events being displayed on another
page)

function check_date ($mysql_timestamp, $days) {

    $timestamp = mktime(0, 0, 0, substr($mysql_timestamp, 4, 2),
substr($mysql_timestamp, 6, 2), substr($mysql_timestamp, 0, 4));
    $event_day = date("z", $timestamp);
    $event_year = date("Y", $timestamp);
    $actual_day = date("z");
    $actual_year =  date("Y");

    while ($event_year > $actual_year) {
        $event_day = $event_day + 365;
        $event_year--;
    }

    if (($event_day - $actual_day) <= $days && $event_day >=
$actual_day) { return TRUE; }

    else { return FALSE; }
}


Then, to display the events that fill this criteria, there is this
code for the date:

function short_date ($mysql_timestamp) {
    $stimestamp = mktime(0, 0, 0, substr($mysql_timestamp, 4, 2),
substr($mysql_timestamp, 6, 2), substr($mysql_timestamp, 0, 4));
    $sformatted_date = date("D M j", $stimestamp);
    return $sformatted_date;
}


My problem is that I have events dated for Sep 2007 and on, and yet
they all come up as being on Dec 7 to 9, 2006..  any ideas?
