VistasIs there a way to change your timezone in Chrome devtools?
I've created a tool in JavaScript that determines the current UTC time and checks if another predetermined date has passed yet.
I'd like to change my browser to another timezone and see if the tests still pass but I'm having trouble finding a way to do this.
Is there a way to do this in Chrome dev tools? If not, do any other suggestions come to mind?

To do this in Chrome Dev tools you can use the Geolocation sensor emulation. Go to the 3 dotted menu, More Tools and Sensors.
There's a Geolocation dropdown with some common locations but you can change your preferred one as well. To do that you can choose Other... in that dropdown and enter a custom Timezone ID
Here's a demo page to test it: https://mathiasbynens.be/demo/timezone and a video that shows the procedure: https://www.youtube.com/watch?v=pIpN_AuV4AI

2020 update: see the other answer, which shows the result of a feature request I filed with Chromium to implement a way to override the timezone.
Note that the technique only works to change the location (including timezone) in that tab. Other tabs will still use the system's timezone. DevTools isn't a reliable way to spoof your timezone.
To change the timezone for all tabs in the browser (Chrome or Firefox or whatever), on Linux/MacOS, you can launch the browser with the TZ environment variable set to the desired timezone name:
TZ=America/New_York chromium-browser
