Hi, Assume org-extend-today-until is set to an integer greater 0, say 3. When I change a timestamp without date such as <2023-01-20> (e.g, when rescheduling), the prompt defaults to a day earlier, i.e., to "2023-01- 19" in this case. The same happens with <2023-01-20 01:00> which is still before 3am. That's very confusing, in particular in the case when the old timestamp only has a date but no time. But even when the old timestamp has has a time, org should never suggest yesterday. I think a good rule of thumb here is that if the user just presses Enter without having typed anything at the prompt, the timestamp shouldn't change at all.
The bug happens because org-read-date tries to take into account the value of org-extend-today-until but it should probably do this when the default time suggested to the user is taken from the current wallclock time, not when it's taken from an existing timestamp. A similar issue when capturing has been reported and fixed here: https://lists.gnu.org/archive/html/emacs-orgmode/2019-06/msg00056.html (Please include me in CC for now, I haven't subscribed to mailing list.) Best, Tim PS: Thanks for org-mode. It has my changed my life.
