常见的想当然
A strong implementation instinct is that `jest.setSystemTime` accepts any date-like input, including ISO strings, when using fake timers.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- 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.
