Frequently Asked Questions

A Unix timestamp (or epoch time) is the number of seconds since January 1, 1970 00:00:00 UTC. It's a standard way to represent time in computing.

Unix timestamps in seconds are 10 digits (e.g., 1699999999). Milliseconds are 13 digits (e.g., 1699999999000). JavaScript uses milliseconds, Unix uses seconds.

Yes. All conversions happen in your browser. No data is sent to any server.

32-bit systems using signed integers will overflow on January 19, 2038. This tool uses JavaScript which handles dates well beyond that.

The current Unix timestamp is shown at the top of the tool and updates in real-time. Click 'Use Current' to copy it to the input.

Unix was created in the late 1960s and officially launched in 1970. The developers chose the system's release year as the epoch. It became the standard for all Unix-like systems.

JavaScript: Date.now() or new Date().getTime(). Python: time.time(). PHP: time(). Most languages have built-in functions to get the current timestamp.

Yes. Negative timestamps represent dates before January 1, 1970. For example, -86400 is December 31, 1969.

Unix timestamps are always in UTC (Coordinated Universal Time). They represent a specific moment in time independent of timezone. Display in local time requires conversion.

Standard Unix timestamps are accurate to the second. Millisecond timestamps add three decimal places. For higher precision, some systems use microseconds or nanoseconds.
