Failed to get key 'timezone' in Google Chrome 71.0.3578.80 on Windows 7

[ema394]

Scenario

• What causes the fingerprint to change? Timezone key is undefined on Google Chrome (release 71.0.3578.80) with Windows 7 as OS so this causes the fingerprint to change.
• What device and browser are you using? Google Chrome 71.0.3578.80 on Windows 7 - U.A. Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36
• What version of fingerprintjs are you using? (Bug reports not applicable to fingerprintjs master are subject to be closed without comment.) 2.0.3

What's the result of evaluating new window.Intl.DateTimeFormat().resolvedOptions().timeZone in that environment?

[ema394]

The result is "undefined"

[jonashaag]

Interesting. What's your system timezone?

[jonashaag]

Can you post the output of new window.Intl.DateTimeFormat().resolvedOptions()

Europe/Rome

OK no idea how this happens. Marking as needinfo, maybe someone else has seen the same behaviour.

It's a known issue in Chrome 71 that only affects Windows 7. The fix will be included in next minor patch update, to be released soon.
