Both my friend and I have the same problem, a wall switch box with
only two wires and a ground entering the switch box. We both had
24-hour timers that worked fine; we both bought replacements to find
that they need 3 wires, they need the neutral. There were no
insturctions on the outside of the packaging.

Do they still sell timers that need only two wires?

Intermatic still makes timers that don't require a neutral. Without a
neutral the timer relies either on an internal battery or a trickle
current through the lamp filament to operate the timer. In the latter
case the timer works only with incandescent lamps. Thanks to our
legislative nannies such timers will not work in many applications,
hence their scarcity in the marketplace.
