+=item change_later OPTION => VALUE...
+
+Schedule a package change for a later date. This actually orders the new
+package immediately, but sets its start date for a future date, and sets
+the current package to expire on the same date.
+
+If the package is already scheduled for a change, this can be called with
+'start_date' to change the scheduled date, or with pkgpart and/or
+locationnum to modify the package change. To cancel the scheduled change
+entirely, see C<abort_change>.
+
+Options include:
+
+=over 4
+
+=item start_date
+
+The date for the package change. Required, and must be in the future.
+
+=item pkgpart
+
+=item locationnum
+
+=item quantity
+
+The pkgpart. locationnum, and quantity of the new package, with the same
+meaning as in C<change>.
