About Unix Timestamps

A Unix timestamp (also called Epoch time or POSIX time) counts the number of seconds since January 1, 1970 00:00:00 UTC. It provides a universal, timezone-agnostic way to represent a point in time as a single number.

What is a Unix Timestamp?

  • Seconds since epoch - counts from January 1, 1970 00:00:00 UTC
  • Universal - the same timestamp represents the same instant worldwide
  • Timezone-agnostic - no timezone information embedded; always UTC
  • Compact - a single integer represents a precise moment in time
