Question 1

What is a Unix timestamp?

Accepted Answer

A Unix timestamp (epoch time) is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970. It is a standard way to represent a moment in time without time zone ambiguity, widely used in databases, APIs, and programming.

Question 2

What is the difference between seconds and milliseconds timestamps?

Accepted Answer

Most systems use seconds (10 digits around 2024). JavaScript and some systems use milliseconds (13 digits). This tool auto-detects milliseconds timestamps and converts them to seconds automatically.

Question 3

What is the maximum Unix timestamp?

Accepted Answer

The 32-bit Unix timestamp will overflow on 19 January 2038 (the "Year 2038 problem"). 64-bit systems extend this far beyond human timescales.
