 * Purpose: Parse about any Arabic textual datetime description into

 * ----------------------------------------------------------------------
 * 
 * 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>
