Thank you kindly, Neil Smith and Brent Baisley.
I now see the error of my approach.
---------------------------------------------------------------------------------------------------------------
$dateArray = array();
> for($counter = 0; $counter <= 3600; $counter++)
> {
> $dateArray[ date("Y.m.d H:i:s", $now - $counter) ] =
> (int)ceil(980 - ($counter * .2333333333333)));
> }

works just fine.
note:
Brent, the array(3601) was coming from the $counter loop above and is the
seconds in an hour plus one ( for aesthetic reasons ).
