Timestamp to Timezone
Convert UNIX timestamps to any timezone instantly
Convert UNIX timestamps and ISO dates to any IANA timezone. Fast, private, runs in your browser. Compare multiple timezones side by side.
Hey Product Hunt 👋
I'm Arthur, the maker of zonestamp.one. This started as a personal itch: I was tired of googling "convert UNI
X timestamp to EST" every time I read a database log.
The tool is intentionally simple:
→ Paste a timestamp
→ Pick a timezone
→ Done.
But under the hood it handles edge cases properly — auto-detecting seconds vs milliseconds vs microseconds, h
andling DST transitions correctly via the browser's Intl API, and supporting all 400+ IANA timezones.
Three design choices I'd love feedback on:
1. **Privacy by default.** No server, no tracking. Is that a selling point or do most users not care?
2. **The dark UI.** I went with a muted dark theme (OKLCH color space). Too niche or just right for dev tools
?
3. **SEO-driven sub-pages.** There are 250+ dedicated pages for specific timezones and countries (e.g. /timez
one/cst/, /country/jp/). Useful or overkill?
This is completely free, no account needed. I'm not monetizing it — just wanted to make something clean and f
ast.
Happy to answer any questions or take feature requests!
