Apparently, you get
`"* A\n** B\n*** 1970\n**** 1970-01 January\n***** 1970-01-01 Thursday\n****** H1 
Capture text\n** C\n"'

Whereas I get the expected result of
`"* A\n** B\n*** 1969\n**** 1969-12 December\n***** 1969-12-31 Wednesday\n****** H1 
Capture text\n** C\n"'

What do you get if you evaluate `(calendar-gregorian-from-absolute 
(time-to-days 0))'? I get `(12 31 1969)'.
I set `org-overriding-default-time' to `0' for testing with datetree.

So I've written a test for lambda-based target.

(should
   (equal
    "* A\n* B\n** H1 Capture text\n* C\n"
    (org-test-with-temp-text-in-file "* A\n* B\n* C\n"
      (let* ((file (buffer-file-name))
             (org-capture-templates
              `(("t" "Todo" entry (file+headline ,file ,(lambda () "B")) "** H1 
%?"))))
        (org-capture nil "t")
        (insert "Capture text")
        (org-capture-finalize))
      (buffer-string))))

But it does not verify that the lambda `(lambda () "B")' is actually being 
called while
visiting the file which would allow reading the file to compute or generate a 
headline.
So I'm wondering if I should write a test for that too. Maybe for each new 
lambda target?
