Frequently asked questions
Seconds or milliseconds?+
Both. Ten-digit numbers are read as seconds and thirteen-digit as milliseconds, which covers nearly every timestamp you'll meet.
Which timezone?+
Output shows UTC and your local time side by side, so there's no ambiguity.
What is a Unix timestamp?+
The number of seconds elapsed since 1 January 1970 UTC. It is how most systems store a moment internally, and it carries no timezone of its own — a timezone only enters the picture when the number is formatted for a person to read.
Can I go the other way, from a date to a timestamp?+
Yes. It converts in both directions, so you can paste a date and get the number, or paste the number and get the date.
