Thanks for the detailed analysis and the patch.

Yes, seems so. The original change came in b61ff117b (org-capture.el:
Set a correct time value with file+datetree+prompt, 2012-09-24), and I
believe the related thread is
I'm okay with the minimal fix to the regexp, though I wonder if we can
avoid the follow-up call to org-read-date-analyze entirely. I'm running
out of time to test thoroughly tonight, but perhaps something like this
(ignoring the potential cond->if cleanup):

Hmm, I haven't wrapped my head around that enough to know what I think,
but perhaps the thread I pointed to above is relevant, at least for

Judging by org-plain-time-of-day-regexp, mixed case (e.g. "Pm") is
Also, you could make it so that the reader doesn't need to count regexp
groups by dropping the trailing group and then just using an empty
string with replace-match. Non-capturing groups could also be used,
though that'd make an already long regexp longer.
