I have no idea how you got that impression. The functions are
complements.

`format-date` takes a date and a format specification and
returns a string describing the date formatted according to the
specification.

`parse-date` takes an arbitrary string and a format specification
and returns the date that the string describes according to the
format specification.

One function does the opposite of the other.

The result is the same, but thatâ??s only because the format you
picked, `yyyy`, produces strings that can be interpreted as a
legal XSD type. If you picked a format thatâ??s not, the functions
would do the opposite of one another.
