Hello everyone, I hope this is the right place to post things like this, and that I included enough information. If not, could somebody please tell me where I should go with this and what information you need? A while ago I experimented with calling org-clone-subtree-with-timeshift from an elisp program. I just wanted to clone a subtree without ever touching any timestamps in it. I looked at the documentation and learnt that passing either nil or “” (the empty string) for the second parameter should do exactly that. I tried passing nil first, since I found that semantically more correct than passing “” for “no time shift”, only to notice that this does not do what I want. If the entry to be cloned contains a timestamp, I still get prompted for a repeater, which is then used to change the timestamp in the clones. This does not happen if I pass the empty string, even if the subtree contains timestamps. I don’t know what the intended behaviour of this function is, but in any case, it does not match its documentation. I attached a minimal org file to test the behaviour of the function: Entry A contains no timestamp, while entry B does. In my opinion both calls ;; call 1 (org-clone-subtree-with-timeshift 1 nil) and ;; call 2 (org-clone-subtree-with-timeshift 1 “”) should do the same with both entries, namely create one copy of them, without changing the timestamp if applicable and without prompting for a shift. Call 2 does exactly this for both examples. However, call 1 only does it for entry A. For entry B, it prompts for a repeater to use as a time shift and when entering anything but the empty string, it also uses it to shift the timestamp in entry B.
