What is a Unix Timestamp?
Unix time is a system for describing a point in time, defined as the number of seconds (or milliseconds) that have elapsed since the Unix epoch (midnight UTC on January 1, 1970). It is widely used in databases, backend servers, and network APIs due to its simplicity and computational efficiency.
Unix Seconds vs Milliseconds
Standard Unix timestamps (used in languages like Python or PHP) count in **seconds** (typically 10 digits). Modern Javascript/Node.js uses **milliseconds** (typically 13 digits). This tool lets you switch between formats instantly.
