Random idea: volts as Hours amps as Minutes Resulting wattage drives an iridescent bulb

I suspect you meant "incandescent".

Iridescence essentially would mean it has a groovy, far-out metallic layer making rainbows on the surface. Not bad, but irrelevant.

PS: Neither of those would really communicate the needed information, except as an extreme (11:59 pm would look just like 10:27 pm, but very different from 12:01 am).

Nice! Needs just a tweak to prevent the overshoot and bounce when going from high to low.

For that, you just need to not make the transition from 100% duty cycle to 0% duty cycle instantaneous, but to ramp down linearly the duty cycle over a large fraction of a second or even an entire second. As another poster said, the overshoot may look cool, but I would be worried that a cheap panel voltmeter would not survive a very large number of such shocks.
