Thanks Bastien.  There's actually a subtle but important difference
between the two: when editing a timestamp with a time of day in, e.g.

     <2020-08-27 Thu 17:00>

then the prompt in the minibuffer will be:

     SCHEDULED Date+time [2020-08-27]: 17:00

While the point is after the "17:00", pressing '.' does not cause a
jump to today's date; instead it just appends the '.' character after
the "17:00".  In contrast, C-. successfully jumps to today without
altering the prompt input.  So in this context, C-. is far more useful
than just '.'.

Funnily enough I found that if I first jump to the beginning of
"17:00" via C-a, then they do indeed behave identically.
