I got tired of timestamp converters that make you click through dropdowns to select formats or are buried in ads, so I built one that auto-detects the input and shows all formats at once.

Just paste any timestamp: Unix (seconds/ms), ISO 8601, RFC 2822, whatever, and it instantly converts to 7 common formats with one-click copy. No dropdowns, no ads, no tracking.

Features:

Auto-detection of input format 400+ timezone support with search Date math (add/subtract time units) Duration calculator between two timestamps Bulk conversion (paste multiple, convert all) URL parameters for sharing (?ts=1706745600) Dark mode default

Tech: Pure vanilla JS + day.js (~50KB total), hosted on Cloudflare Pages for free.

I use it daily when debugging API logs or working with different timezone databases. Built it over a weekend to scratch my own itch.
