What is a Unix timestamp?

A Unix timestamp (epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is a universal way to represent a point in time without timezone ambiguity, widely used in databases, APIs, and log files.

What is the difference between seconds and milliseconds?

Unix timestamps are traditionally in seconds (10 digits). JavaScripts Date.now() returns milliseconds (13 digits). Many modern APIs and databases use milliseconds. This tool supports both.

What is the Unix epoch?

The Unix epoch is the reference point: January 1, 1970, 00:00:00 UTC. All Unix timestamps are measured as the number of seconds (or milliseconds) since this moment.

What is the Year 2038 problem?

Systems that store timestamps as a 32-bit signed integer will overflow on January 19, 2038. Modern systems use 64-bit integers, pushing the overflow date billions of years into the future.
