What is a Unix Timestamp?

A Unix timestamp (or Epoch time) is a system for describing a point in time. It is defined as the number of seconds that have elapsed since midnight (UTC) on January 1, 1970, minus leap seconds. It is the standard way computer systems, databases, and APIs store dates internally because integers are much faster to sort and compare than parsed string dates.

Seconds vs Milliseconds

Different programming languages use different default scales. PHP and standard Unix systems measure the epoch in Seconds. JavaScript (and therefore Node.js and many modern web frameworks) measures the epoch in Milliseconds. Our converter automatically detects the magnitude of your number and parses it correctly.
