You connect to a VPN server in Amsterdam, open a site — and it still greets you with a suspiciously accurate "good evening" and shows prices in your home currency. The tunnel is fine. Your clock gave you away. We ran into this often enough to build a tool for it.
Why the timezone betrays your VPN
Any page can read your timezone with one line of JavaScript — Intl.DateTimeFormat().resolvedOptions().timeZone — no permissions, no GPS. The browser answers with the system timezone, not the timezone of your VPN exit. When your IP says Amsterdam and your clock says Asia/Dubai, that mismatch is exactly what anti-fraud systems, streaming services and fingerprinting scripts look for. The VPN moved your address, but not your shadow.
Timezone Spoofer: the browser clock in one click
Timezone Spoofer is our free extension that overrides everything JavaScript can learn about your clock — Date, Intl.DateTimeFormat, offsets, date strings — in every frame of the page, iframes included. Flip the toggle, pick a zone, and the page reloads already living in it.
Inside the database are all 400+ IANA timezones with 33,000+ indexed city names. Search understands cities, countries, regions and offsets: type "Miami" and get America/New_York with its current UTC offset; type "UTC+5" and see every zone that matches right now. Recent picks stay one click away as presets.
Built for VPN use: auto-detect from IP
The feature that pairs with a VPN is auto-detect: the extension checks your current IP and sets the matching timezone automatically. Connect to a VPN exit in another country — the browser clock follows by itself, no manual picking. Turn the VPN off — the clock comes back. The detection endpoint is configurable and off by default.
For sites that must see your real time — a bank, a calendar — there is a per-site exclusion list, and a per-tab badge shows at a glance whether the current page is spoofed, excluded or untouched.
Privacy and price
Everything is stored locally in the browser: no accounts, no analytics, no tracking, nothing transmitted anywhere. The extension is free — no trial tiers, no locked features. English and Russian interface, light, dark and system themes.
It ships for both major engines:
- Chrome (and Chromium browsers): Chrome Web Store
- Safari on macOS and iOS: App Store
The full setup: VPN + matching clock
- Get a VPN key from @unlocknoname_bot in Telegram — the bot issues one with a free 24-hour trial, no email and no card, and the key works in the Noname VPN app (Google Play).
- Install Timezone Spoofer and enable auto-detect from IP in Settings.
- Connect the VPN. The extension reads the new IP and moves your browser clock to the exit's timezone.
IP, clock and locale now tell one story — and the "good evening" finally arrives in the right timezone.
