FAQ
Seconds or milliseconds?
Most tools use seconds (10 digits). JavaScript Date.now() and most APIs use milliseconds (13 digits). We auto-detect by magnitude.
What timezone is used?
Local times use your browser's timezone. ISO 8601 and UTC are timezone-independent. The Unix timestamp itself is always UTC.
Is anything sent to a server?
No. All conversion happens in your browser.
