// This file contains date formats that Frink will parse.// See documentation for SimpleDateParser or docs/index.html for more details.//// Now that regular expressions are possible in Frink, I'd like to replace this// whole mess with a regexp-based solution, which would be more flexible and// more powerful.//// Alan Eliasen//// Symbol       Meaning         Presentation    Example//// G            era designator  Text            AD// y            year            Number          1996// M            month in year   Text & Number   July & 07// d            day in month    Number          10// h            hour in am/pm   Number          12//                  (1-12)// H            hour in day     Number          0//                  (0-23)      // m            minute in hour  Number          30// s            second in min.
