-/**
- * TSimpleDateFormatter class.
- *
- * Formats and parses dates using the SimpleDateFormat pattern.
- * This pattern is compatible with the I18N and java's SimpleDateFormatter.
- *
- * 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
- * ----------------------------------------------------
- *
- *
- * Usage example, to format a date
- *
- * $formatter = new TSimpleDateFormatter("dd/MM/yyy");
- * echo $formatter->format(time());
- *
- *
- * To parse the date string into a date timestamp.
- *
- * $formatter = new TSimpleDateFormatter("d-M-yyy");
- * echo $formatter->parse("24-6-2005");
- *
