I'm looking for a wall clock that has decimal billing markings. I can't find one on the web, instead I keep getting information about rounding time clock entries.

Researchers at the U.S. National Institute of Standards & Technology (NIST) say they have created the most accurate atomic clock to date — one that can measure time down to the 19th decimal place.

Many stop lights at street intersections display a countdown of the remaining seconds before the light changes. If you’re like me, you count this time in your head and then check how in sync you are.
