Unix Timestamp Generator shows the current Unix epoch time - the number of seconds elapsed since January 1, 1970, 00:00:00 UTC - updated live in your browser. This is the universal time standard used by backend APIs, databases, JWT tokens, log files, and distributed systems.
Unix time counts seconds elapsed since the Unix epoch (January 1, 1970, 00:00:00 UTC). It is timezone-independent. JavaScript Date.now() returns milliseconds while Python time.time() returns seconds.
The number of seconds since January 1, 1970, 00:00:00 UTC. It is a timezone-independent integer used universally in computing.
Unix time in seconds is the traditional format (e.g., 1713110400). JavaScript Date.now() returns milliseconds (x1000). Always verify the unit your API expects.
JavaScript: new Date(ts * 1000).toISOString(). Python: datetime.utcfromtimestamp(ts). MySQL: FROM_UNIXTIME(ts). PostgreSQL: TO_TIMESTAMP(ts).
exp = Math.floor(Date.now() / 1000) + lifetimeSeconds. For a 1-hour token: currentUnixTime + 3600.
32-bit signed integers max out at 2,147,483,647 (Jan 19, 2038). Modern 64-bit systems handle timestamps far beyond 2038.
