The QuickToolz Unix Timestamp Converter translates Unix epoch timestamps (seconds or milliseconds) into human-readable dates in your local time and UTC — and vice versa. Auto-detects seconds vs milliseconds and supports any year from 1970 onward.
A Unix (or POSIX) timestamp is the number of seconds elapsed since 1 January 1970 00:00:00 UTC. It’s the universal time representation in Linux, databases, log files, JSON APIs, and many languages. Milliseconds are common in JavaScript (Date.now()).
