Ya know those wind-up timers you sometimes (or used to) see in hotel
bathrooms for the heat lamps? I need to mount one of those, and an outlet in
a metal box. It'll be used for a portable electric heater which we regularly
forget to turn off. For grounding purposes, should the green from the
outlet, timer and cord all be attached to the box itself?

You're putting the box on the end of a cord? Yes, connect the metal
box and all ground wires together. I beleive I've seen those timers
in lowes btw.
