How Unix Time Converter works
How does this Unix time tool work?
It shows a live-updating current Unix timestamp, refreshed every second with setInterval, and separately lets you paste any timestamp - which it classifies as seconds or milliseconds using the same digit-count check (more than 10 digits means milliseconds) before showing the equivalent ISO and local date strings.
What is it used for?
It is a fast way to grab the current epoch value for testing an API or script, or to figure out what unit an unfamiliar timestamp from a log or response is actually in.
How is this different from the timestamp converter tool?
This one is centered on the always-updating live clock and quick unit detection for a single pasted value, while the separate timestamp converter tool is built around converting back and forth with a local date-and-time picker.
