Here is what I think you are looking for.

<?php

# I am guessing that your $days array looks something like this.
$days = array('Sunday',
              'Monday',
              'Tuesday',
              'Wednesday',
              'Thursday',
              'Friday',
              'Saturday');

# Get todays information
$d = getdate();

$endTime = "17:00:00";
list($et_hr, $et_min, $et_sec) = explode(':', $endTime);
$unix_endTime = mktime($et_hr, $et_min, $et_sec,
                       $d['mon'], $d['mday'], $d['year']);

$currentTime="09:00:00";
list($ct_hr, $ct_min, $ct_sec) = explode(':', $currentTime);
$unix_currentTime = mktime($ct_hr, $ct_min, $ct_sec,
                           $d['mon'], $d['mday'], $d['year']);

$interval = 60;

# Calculate how many rows their should be
$num_intervals = floor(($unix_endTime - $unix_currentTime) / $interval);

echo 'Num_INter: ', $num_intervals, '</br>';

echo '<form><table>';

for ( $i=$unix_currentTime; $i <= $unix_endTime; $i=($i+$interval) ) {
  echo '<tr>', '<td>', date('Y/m/d H:i:s', $i), '</td>';

  foreach ($days AS $day) {
    echo '<td>',
         '<input type="radio" name="dateTimeSelection" value="',
         $day,
         '" />',
         $day,
         '</td>';
  }
  # Don't forget to reset the $days array
  # otherwise the array pointer is at the last index
  reset($days);
  echo '</tr>';
}

echo '</table></form>';

?>
