So, basically, this:

* ``format_date(val, format_string)`` -- format the value, which must be a date string, using the format_string, returning a string. It is best if the date is in ISO format as using other date formats often causes errors because the actual date value cannot be unambiguously determined. Note that the ``format_date_field()`` function is both faster and more reliable.
