Frequently asked questions
My timestamp has 13 digits — will this still work?
No — a 13-digit number is usually a JavaScript-style timestamp in milliseconds. Divide it by 1000 first to get seconds before entering it here.
What is the Unix epoch?
1 January 1970, 00:00:00 UTC — the reference point most computer systems use to represent a moment in time as a single number.
Does this convert dates back into a timestamp too?
This page converts timestamp to date only, the far more common lookup (e.g. reading a timestamp from a log file or API response).
