How do I fix a timezone mismatch when using a VPN?

Change your system timezone to match your VPN exit country. On Windows: Settings > Time & Language. On macOS: System Settings > General > Date & Time.

Can websites detect my timezone without JavaScript?

Limited. They can infer it from Accept-Language headers and request timing, but less precisely.

Is timezone alone enough to identify me?

Not uniquely, but combined with other vectors it contributes to a unique identifier.

Does Tor Browser handle timezone correctly?

Yes. Tor Browser standardizes the timezone to UTC for all users.
