This only takes effect when `Temporal` is available on the global object — either natively (Node.js >= 26 by default, behind `--harmony-temporal` on older versions, and supporting browsers) or through a globally installed polyfill such as `import 'temporal-polyfill/global'`. 58 58 + 59 59 + Previously `Temporal.Now` kept returning the real wall-clock time even when [`vi.useFakeTimers()`](/api/vi#vi-usefaketimers) was active. Now it follows the mocked clock: 60 60 + 61 61 + ```ts 62 62 + vi.useFakeTimers({ now: 0 }) 63 63 + 64 64 + Temporal.Now.instant().epochMilliseconds // 0 (was the real time in v4) 65 65 + ``` 66 66 + 67 67 + `Temporal` is part of the default set of faked APIs, so it is controlled by [`fakeTimers.toFake`](/config/#faketimers-tofake) and [`fakeTimers.toNotFake`](/config/#faketimers-tonotfake). To keep `Temporal` native, add it to `toNotFake`: 68 68 + 69 69 + ```ts 70 70 + vi.useFakeTimers({ toNotFake: ['Temporal'] }) 71 71 + ``` 72 72 + 55 73 ### Removed `test.sequential`, `describe.sequential`, and `sequential` Options 56 74 57 75 Vitest 5.0 removes the deprecated `test.sequential`, `describe.sequential`, and `sequential` test options. Use `concurrent: false` when you need a test or suite to opt out of inherited or globally configured concurrency.
