Convert between Unix timestamps and human-readable dates
Add to Chrome★★★★★ 0 out of 5

Whitebrook Lane was built by Arthur D to solve a specific, recurring annoyance. During a long debugging session, you hit a timestamp in a log or an API payload, and you have to stop, open a new tab, find a converter site, paste the value, wait for the page to load, and then navigate back. That interruption is small on its own, but it compounds across a working day. The extension puts the conversion one click away from wherever you already are.
The extension is listed in the Chrome Web Store under Developer Tools and is available in English. It was designed to stay out of your way: no permissions to read page content, no background service worker phoning home, no onboarding flow. The popup opens, you convert, you close it. Arthur D made the deliberate choice to collect no user data at all, which is disclosed plainly on the store listing. For developers who work in environments with strict data-handling policies, that matters.
Yes. The conversion is a local calculation performed entirely inside the extension. It does not contact any external server, so it works offline without any limitation. This includes air-gapped machines and networks with restricted outbound access.
None. Arthur D, the developer, has disclosed on the Chrome Web Store listing that no user data is collected or used. Nothing you type into the popup is stored, transmitted, or logged anywhere.
Yes. The extension handles both Unix timestamps in seconds (10 digits, e.g. 1719187200) and in milliseconds (13 digits, e.g. 1719187200000). It detects the format automatically, so you do not need to convert manually before pasting.
No. The extension operates entirely through its toolbar popup. It does not inject content scripts into web pages, does not read the content of pages you visit, and does not modify any page you have open.
Yes, it is free to install from the Chrome Web Store. There is no paid tier, no subscription, and no in-extension purchase. You install it and it works.
