O que costuma-se supor

A strong implementation instinct is that `jest.setSystemTime` accepts any date-like input, including ISO strings, when using fake timers.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• Calling `jest.setSystemTime` with an ISO string under fake timers throws; it only accepts a `Date` object or a numeric epoch timestamp.
• After `jest.useFakeTimers()` and `jest.setSystemTime(new Date('2020-01-02T00:00:00.000Z'))`, `Date.now()` equals that date's epoch milliseconds.
