From manual page: http://www.php.net/function.strftime
---

I develope an function to fix Problems/bug of strftime in Windows (XAMPP).

Test script:
---------------
        function strftime_win32($format, $ts = null) { 
                if (!$ts) $ts = time(); 
        
                $mapping = array( 
                                '%C' => sprintf("%02d", date("Y", $ts) / 100), 
                                '%D' => '%m/%d/%y', 
                                '%e' => sprintf("%' 2d", date("j", $ts)), 
                                '%h' => '%b', 
                                '%n' => "\n", 
                                '%r' => date("h:i:s", $ts) . " %p", 
                                '%R' => date("H:i", $ts), 
                                '%t' => "\t", 
                                '%T' => '%H:%M:%S', 
                                '%u' => ($w = date("w", $ts)) ? $w : 7 
                ); 
                $format = str_replace( 
                                array_keys($mapping), 
                                array_values($mapping), 
                                $format 
                ); 
                
                if($format=='%V' or $format=='%G' or $format=='%g'){ 
                        // When strftime("%V") fails, some unoptimized workaround 
                        // 
                        // http://en.wikipedia.org/wiki/ISO_8601 : week 1 is "the week with the year's first Thursday in it (the formal ISO definition)"

                        
                        $year = strftime("%Y", $ts);
