I asked about a way to specify a time when using org-resolve-clock instead
of a number of minutes:

https://lists.gnu.org/archive/html/emacs-orgmode/2020-01/msg00010.html

I've implemented this myself and a patch is attached. Comments welcome --
my change works, but I'm not sure about coding style, and right now there's
no error checking.

I marked the patch as a tiny change, but it does add a new menu option and
behavior to org-resolve-clock, so there may be an argument that it's not,
from a user perspective, a "tiny change", but code-wise it's quite simple:
the core logic really isn't more than "ask the user for a time and
subtract".

I hope this change can be incorporated into the official Org release.

Regards,

Dan
