Ask HN: Short story that was posted to HN

Trying to locate a short story that I believe was posted here a few months ago. It took place on a spaceship that contained a digital archive of all of human knowledge. At some point, one of the characters made a grave error and overwrote some important mathematical constants, causing the ship to start making erroneous computations. They noticed that the time on their wrist watch was drifting away from the time on the ship's main computer.

Any ideas? Searching the web didn't turn anything up.
