/**
 * TSimpleDateFormatter class.
 *
 * Formats and parses dates using the SimpleDateFormat pattern.
 * This pattern is compatible with the I18N and java's SimpleDateFormatter.
 * <code>
 * Pattern |      Description
 * ----------------------------------------------------
 * d       | Day of month 1 to 31, no padding
 * dd      | Day of monath 01 to 31, zero leading
 * M       | Month digit 1 to 12, no padding
 * MM      | Month digit 01 to 12, zero leading
 * yy      | 2 year digit, e.g., 96, 05
 * yyyy    | 4 year digit, e.g., 2005
 * ----------------------------------------------------
 * </code>
 *
 * Usage example, to format a date
 * <code>
 * $formatter = new TSimpleDateFormatter("dd/MM/yyy");
 * echo $formatter->format(time());
 * </code>
 *
 * To parse the date string into a date timestamp.
 * <code>
 * $formatter = new TSimpleDateFormatter("d-M-yyy");
 * echo $formatter->parse("24-6-2005");
 * </code>
