[PHP] strtotime Question

[gohaku]

Hi everyone,
I made the mistake of using strtotime("day") instead of 
strtotime("today")
to get the current time.
I was just curious, what is strtotime("day") represent?

Below is what I used to test the "day" and "today" parameters:

Testing One Minute Difference<br>
<?
echo min_diff();
function min_diff()
{
        $now = strtotime("today");//Return value is 60
        //$now = strtotime("day");//Return value is 86400
        $onemin = strtotime("-1 minute");
        return $now-$onemin;
}
?>
Thanks in advance.
