what is a date tree? This:

,----
| *  <2014-10-28 Di>
`----

?

If the date-tree is the parent and has a timestamp, then the entries
are part of the contents of parent, and you can use this function to
map over the parents

,----[ C-h f org-element-map RET ]
| org-element-map is a compiled Lisp function in `org-element.el'.
| 
| (org-element-map DATA TYPES FUN &optional INFO FIRST-MATCH
| NO-RECURSION WITH-AFFILIATED)
| 
| Map a function on selected elements or objects. [...]
`----

and this to get their contents

,----[ C-h f org-element-contents RET ]
| org-element-contents is a compiled Lisp function in `org-element.el'.
| 
| (org-element-contents ELEMENT)
| 
| Extract contents from an ELEMENT.
`----

and then 'org-element-property' and 'org-element-put-property' to get
and set timestamp info from the parent and any other info from the child
entries.
