A non well formed numeric value Error

[mark1million]

Nabeel,

I keep getting this when the maintenance cron is run,

PHP Notice: A non well formed numeric value encountered in /core/common/StatsData.class.php on line 89

This is the block,

/**
    * Get all of the months since a certain date
    */
   public static function getMonthsSinceDate($start) {
       $key_month = date('MY', $start); //This is line 89
       $key = 'months_since_' . $key_month;
       $months = CodonCache::read($key);

       if ($months === false) {
           if (!is_numeric($start)) {
               $start = strtotime($start);
           }

           $end = date('Ym');

           do {
               # Get the months
               $month = date('M Y', $start); 
               $months[$month] = $start; # Set the timestamp
               $start = strtotime('+1 month +1 day', strtotime($month));

               # Convert to YYYYMM to compare
               $check = intval(date('Ym', $start));

           } while ($check <= $end);

           CodonCache::write($key, $months, 'long');
       }

       return $months;
   }

That's fine, it's not an error, just a notice
