1. Way easier solution with

       page.evaluate(() => {
         Date.now = () => {
           return 1609477200000; //Jan 1, 2021
         };
       });

2. You can use mocking tools like TimeShift.
   This piece of code would inject the timeshift library and then then the date to Feb 02 2012:

   const playwright = require("playwright");
   
   (async () => {
   
       let removed = false;
       const browser = await playwright["chromium"].launch({headless: false});
       const page = await browser.newPage();
       await page.setContent('<a href="#" onclick="document.querySelector(\'span\').innerText = new Date().toString()">Test me</a><span></span>');
       await page.click('a');
       console.log(await page.innerText('span'));
       await page.addScriptTag({ url: 'https://cdn.jsdelivr.net/npm/timeshift-js@1.1.1/timeshift.js'});
       await page.evaluate(() => {
           Date = TimeShift.Date; 
           TimeShift.setTime(1328230923000); 
       });
       await page.click('a');
       console.log(await page.innerText('span'));
       browser.close();
   })();
   

   Output:

   Fri Sep 18 2020 15:06:58 GMT-0300 (Argentina Standard Time)
   Thu Feb 02 2012 22:02:03 GMT-0300
