*
* Arabic StrToTime Class
*
* PHP class to parse about any Arabic textual datetime description into
* a Unix timestamp.
*
* The function expects to be given a string containing an Arabic date format
* and will try to parse that format into a Unix timestamp (the number of seconds
* since January 1 1970 00:00:00 GMT), relative to the timestamp given in now, or
* the current time if none is supplied.
*
* Example:
* <code>
* date_default_timezone_set('UTC');
* $time = time();
*
* echo date('l dS F Y', $time);
* echo ' ';
*
* include('./I18N/Arabic.php');
* $obj = new I18N_Arabic('StrToTime');
*
* $int = $obj->strtotime($str, $time);
* $date = date('l dS F Y', $int);
* echo "Arabic String: $str ";
* echo "Unix Timestamp: $int ";
* echo "Formated Date: $date ";
* </code>
