Why is my timezone not being set in Cypress with moment-timezone library?

[zubairrshahidd]

Need a way to set Browser's Timezone in Cypress

I have used moment-timezone library

1. Added in support>index.js const moment = require('moment-timezone');
2. Added TZ env variable in my cypress.config.js

"env": {
      "TZ": "America/New_York"
    },

3. set the timezone to in by beforeEach hook

beforeEach(() => {
 moment.tz.setDefault('America/New_York');
})

4. it block contains the assertion

const browserTimeZone = moment.tz.guess(); 
expect(browserTimeZone).to.equal('America/New_York');

But it is not setting up the timezone, the assertion is failing
