What caught me out is the fact that you can have a forward repeat for
dates but not for times, e.g.

REM 22 Jan 2010 *1 MSG do this everyday

whereas the timed reminder with a trepeat will stop at the specified
time.

Therefore, as you suggest below, I have to specify the end time, and
work my way back.

In principle, this is what I want, but from 10:00 (am) to midnight. How
do I express midnight? I tried 24:00 and 00:00 - neither work. I seem
to remember that timed reminders can't span midnight. Maybe that's the
problem.
