    1970/13/03 23:22:01
    
    The function is "safe" i.e. non-dateTime data (like the word "Unknown") can be passed in and is sorted properly.
    
    UPDATE 08/01/2009: 1. Full or Short-hand english month names (e.g. "March" or "Mar") now require a space
                       or a comma after them to be properly parsed.
                       2. If no timestamp is given, a fake timestamp "00:00:00" is added to the string this enables
                       the function to parse both date and datetime data.
