-// HISTORY
-// ------------------------------------------------------------------
-// May 17, 2003:   Fixed bug in parseDate() for dates <1970
-// March 11, 2003: Added parseDate() function
-// March 11, 2003: Added "NNN" formatting option. Doesn't match up
-//                 perfectly with SimpleDateFormat formats, but 
-//                 backwards-compatability was required.
-
-// ------------------------------------------------------------------
-// These functions use the same 'format' strings as the 
-// java.text.SimpleDateFormat class, with minor exceptions.
-// The format string consists of the following abbreviations:
-// 
-// 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"
