  Just use the usual difference operator:

    xs:dateTime("2006-05-30T13:38:00")
      - xs:dateTime("2006-05-29T13:38:00")
       ==> P1D

  The functions used to define the operators are not usable
by the user.  Not by name.  But the same semantics can be
accessed via the several operators, as stated in §B.2,
"Operator Mapping", in the XQuery CR.
