Questions
What is a Unix timestamp?
Seconds since 1970-01-01 00:00:00 UTC. The same moment has the same value in every time zone.
Seconds or milliseconds?
13 digits or more is read as milliseconds; fewer as seconds. JavaScript's Date.now() is in milliseconds.
What about the year 2038 problem?
Systems storing seconds in a signed 32-bit integer overflow on 19 January 2038. This tool uses 64-bit numbers and is not affected.
Are leap seconds counted?
Unix time ignores leap seconds, and so does this tool.
Is anything saved?
No. It is calculated in your browser.
