How to remove "date" from the response?

It messes with inline snapshot tests.

it('fetches url that produces 500', async () => {
  await runWithTestServer(async ({ url }) => {
    const response = await fetchUrl(url + '/internal-server-error');

    expect(response).toMatchInlineSnapshot(`
      {
        "body": "",
        "headers": {
          "connection": "keep-alive",
          "content-length": "0",
          "content-type": "text/plain;charset=UTF-8",
          "date": "Sun, 24 Dec 2023 15:20:15 GMT",
          "keep-alive": "timeout=5",
        },
        "statusCode": 500,
      }
    `);
  });
});

Would like the response not to contain date.

I guess when you write tests, due to time changes, this can lead to incorrect snapshot matches. You can start by mocking the system time.
in bun

import { setSystemTime, beforeAll, test, expect } from "bun:test";

beforeAll(() => {
  setSystemTime(new Date("2020-01-01T00:00:00.000Z"));
});

test("it is 2020", () => {
  expect(new Date().getFullYear()).toBe(2020);
});

in vitest

test('mocking the system time', () => {
  vi.useFakeTimers();

  // Set the current date to a specific point in time
  const now = new Date('2023-04-20');
  vi.setSystemTime(now);

  // Now `Date.now()` and `new Date()` will use the time set above
  expect(Date.now()).toBe(now.getTime());

  // When you want to restore the original timers
  vi.useRealTimers();
});
