====================================================================

These are the parts of the format string - similar to C#
but not quite.

Field        | Full Form          | Short Form
-------------+--------------------+-----------------------
Year         | yyyy (4 digits)    | yy (2 digits), y (2 or 4 digits)
Month        | MMM (name or abbr.)| MM (2 digits), M (1 or 2 digits)
             | NNN (abbr.)        |
Day of Month | dd (2 digits)      | d (1 or 2 digits)
Day of Week  | EE (name)          | E (abbr)
Hour (1-12)  | hh (2 digits)      | h (1 or 2 digits)
Hour (0-23)  | HH (2 digits)      | H (1 or 2 digits)
Hour (0-11)  | KK (2 digits)      | K (1 or 2 digits)
Hour (1-24)  | kk (2 digits)      | k (1 or 2 digits)
Minute       | mm (2 digits)      | m (1 or 2 digits)
Second       | ss (2 digits)      | s (1 or 2 digits)
AM/PM        | a                  |

NOTE THE DIFFERENCE BETWEEN MM and mm! Month=MM, not mm!
Examples:
 "MMM d, y" matches: January 01, 2000
                     Dec 1, 1900
                     Nov 20, 00
 "M/d/yy"   matches: 01/20/00
                     9/2/00
 "MMM dd, yyyy hh:mm:ssa" matches: "January 01, 2000 12:30:45AM"
