Frequently Asked Questions

What is a Unix timestamp?

A Unix timestamp (also known as Unix time, POSIX time, or epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. This moment is called the Unix epoch. It's widely used in programming and databases for storing date/time values.

How do I convert a 13-digit timestamp?

13-digit timestamps represent milliseconds since the Unix epoch. Our converter automatically detects whether you've entered seconds (10 digits) or milliseconds (13 digits) and converts accordingly. Simply paste your timestamp and click convert.

What's the difference between UTC and local time?

Unix timestamps are always in UTC (Coordinated Universal Time). When converting to a human-readable date, our tool shows both UTC and your local timezone. This helps avoid confusion when working with international systems.

Why use Unix timestamps?

Unix timestamps are timezone-agnostic, making them perfect for storing dates in databases and APIs. They're simple integers that are easy to compare, sort, and calculate time differences. Most programming languages have built-in functions to work with Unix timestamps.

What is the Year 2038 problem?

The Year 2038 problem occurs because many systems store Unix timestamps as signed 32-bit integers, which can only represent dates up to January 19, 2038 03:14:07 UTC. Modern systems use 64-bit integers to avoid this limitation.
