Timestamp Tips
Understand how Unix time works to avoid common pitfalls.
Seconds vs Milliseconds
JavaScript's Date.now() returns milliseconds while most other languages and APIs use seconds. Watch out for the 1000x mismatch when passing values around.
The Unix Epoch
Unix time counts from January 1, 1970 at 00:00:00 UTC. That moment is timestamp zero, and everything is measured relative to it.
Timezone Independent
A timestamp represents the same instant everywhere on Earth. Only its display as a human-readable date depends on the chosen timezone.
Everyday Uses
Timestamps are handy for API debugging, log analysis, and cache-busting where you need a unique, monotonic value.
