Almost surely, "Arrival" and "Departure" are strings and
not "DateTime" objects.
Unlike "DateTime" objects, strings do not have an "ISO" method.
Therefore, "ISO" is interpreted as a (C) format string.
As it does not contain format specifiers ("%spec"), it is
unable to convert the argument.

You find details about the "fmt" attribute in

Your problem will go away when "Arrival" (and friends) are
"DateTime" objects.
Depending on their format, you may be able to use:

      <dtml-var expr="ZopeTime(Arrival)" fmt=ISO>
