What a Unix timestamp is
A Unix timestamp counts seconds (or milliseconds, in JavaScript's case) since midnight UTC on January 1, 1970 — the "Unix epoch." It's timezone-independent by design, which is exactly why it's the standard way to store and pass dates between systems: the same number means the same instant everywhere, and each system converts it to a local display time only when showing it to a person.
Frequently asked questions
What exactly is a Unix timestamp?
The number of seconds (sometimes milliseconds) elapsed since midnight UTC on January 1, 1970 — a compact, timezone-independent way to represent a specific moment in time that's universal across systems.
Why does the same timestamp show a different time in different apps?
The underlying UTC moment is identical — what differs is the local timezone used to display it. Always check whether a tool or system is showing you local time or UTC when comparing timestamps.
