Time ZonesTime Zones
The time in the places you work with, at a glance, and a converter for finding a meeting time.
What it does
Small and quiet, it lives in the tray. Click the icon and it opens next to the clock; click away and it hides.
Everyone's time at a glance
Add cities, countries or zones and see each one next to yours, with a hint when it's working hours, evening or night there.
Convert a meeting time
Shift the time forward or back and see it in every place at once, including yesterday and tomorrow.
Copy as one line
Paste the converted times into a meeting invite or a chat with Copy as text.
Times in the tray
Hover the tray icon to see your first three places without opening anything.
Your format, your names
12 or 24 hour clock, your own working hours, and a name for this computer's place.
Privacy in short
- On your PC
- Your list of places and your settings. Stored in your Windows user profile and never uploaded by Time Zones.
- Bandwidth sharing
- EarnFM processes your IP address, a device ID and your consent record to run the sharing, based on your consent.
- Usage statistics
- Time Zones sends usage statistics to PostHog (EU): a random install ID, app and Windows version, sharing and settings status, feature use counts, crash summaries and, once you've agreed, recordings of how its window is used with your content hidden. Never your clipboard, snippets, what you type or window titles. No account, no ads.
- This website
- PostHog analytics and page recordings without cookies, to see which pages and campaigns lead to downloads and how the pages are used. It's served by Cloudflare, which handles your IP address to deliver the pages.
Questions
What do I need to run it?
Windows 10 or Windows 11, 64-bit. It installs for your Windows account only, so you don't need administrator rights. Time Zones uses Microsoft Edge WebView2, which is part of Windows 11 and most Windows 10 PCs; if it's missing, the installer fetches it.
Windows says it protected my PC. Is the download safe?
New downloads build trust with Microsoft's SmartScreen over time, so Windows may show "Windows protected your PC" for a while. The installer is signed by TeraShift GmbH. Check that the publisher shown is TeraShift GmbH, then choose More info and Run anyway.
Is it really free?
Yes. Every feature is included, with no ads, trials or purchases. Time Zones is paid for by sharing a little unused bandwidth, which you agree to when you first open it. How that works.
Can I use it without sharing bandwidth?
No. Sharing is what keeps Time Zones free, so the app asks first and only runs if you agree. If you choose "No thanks, quit", nothing is shared and the app closes.
Will it slow down my internet?
It's built to use only bandwidth you aren't using, and it stops while Time Zones isn't running. If you notice a difference you're unhappy with, uninstalling stops it completely.
How do I stop sharing or uninstall?
Uninstall Time Zones: open Windows Settings, then Apps, then Installed apps, find Time Zones and choose Uninstall. Sharing stops as soon as it's uninstalled. In the app, Settings, then Stop sharing, takes you to the same place. Step-by-step instructions.
What data does it collect?
The app's own data (your list of places and your settings) stays on your PC. For bandwidth sharing, EarnFM processes your IP address, a device ID and a record of your consent. Time Zones also sends usage statistics to PostHog, our analytics service in the EU: a random install ID, the app and Windows version, whether sharing and Start with Windows are on, which settings are switched on and how often features are used. Once you've agreed, it also records how its window is used, with your own content (clipboard items, snippets, app names, places) and input fields hidden. It never sends what you copy, type or store, or window titles. Details are in the privacy policy.
Does it start with Windows?
Yes, quietly in the tray, so it's there when you need it. You can turn that off in Time Zones's Settings. Anything that would interrupt you, like notifications or shortcuts, is off until you turn it on.
Does it need the internet?
No. Times are calculated on your PC from Windows' clock and built-in time zone data.
