From the latin words Tempum (“Time”) and Scopeo (“to guard”).
Something which guards the value of Time.
A Temposcopium has the shape of a common watch, but it won’t work the way a watch works. A Temposcopium has no gear nor battery, its hands are still and won’t ever tick around, but still a Temposcopium will always tell the truth about Time.
for we do not need to measure Time,
we just need to be present
