What with all the various eco topics concerning when and how to run your
heating/cooling,
I have yet to see a home electronic thermostat with the added feature of -
- an elapsed run timer -

ie - how long has the system run since timer reset ?

This would be great to see if setting the temp higher in summer,
or a little lower in winter actually changes anything
while being able to record the amount of time the furnace or A/C runs...

The Nest thermostat does this. The web site will show you time used
for every day in the last month and they send an email each month with
all of the details. I certainly wouldn't spend the money just for
that but it really is a nice thermostat, particularly to monitor a
vacant or vacation house.
