I made a self-hosted, single-HTML-file timezone wall for tracking timezone (working hours) for my global team.

I got tired of constantly googling "what time is it in [city]?" to schedule meetings with my remote team. I wanted a simple, at-a-glance view of everyone's local time, but I didn't want yet another cloud service or a heavy app for something so simple.

So, I built Team Timezone Wall with Cursor. Honestly its no feat of engineering or super complicated but solves once specific problem and has been my daily use tool for months now. Quite sticky!

For the self-hosting and privacy-minded folks here, the best part is its simplicity:

- It's a single index.html file. No dependencies, no build steps, no external scripts.

- Zero tracking and completely server-less. It runs entirely in your browser. Nothing is sent anywhere.

- Infinitely portable. You can host it yourself on any static web server, use it with file:///, or just pass the file around.

It's a small tool, but it solves a real headache for me without compromising on privacy or simplicity.
