[O] short timestamp in org-log-note-headings

[John J Foerch]

Hello,

I wonder if a format code could be added for org-log-note-headings that
allows the insertion of a short timestamp (without clock time).  The use
case for this is that I log state changes of to-do items, but the
precise time of the state change is usually more information than I want
to record.

Thank you
