The cast isn't necessary, but it's more efficient. Internally, it basically
doing the equivalent of casting to DateTime every time you ask for the
pieces of the date/time such as the year or hour. So, whether is casting is
better or not depends on whether you want shorter code or faster code.

If that's what you want, then just cast to Date and call toISOExtString() on
it.
