Convert Unix epoch time to a readable date
Unix time is common in APIs, databases, analytics exports, server logs, and developer tools. Paste a timestamp to see the corresponding date in your device time zone and the exact UTC ISO 8601 representation.
Ten-digit values are usually seconds, while 13-digit values are usually milliseconds. OmniKit detects the unit automatically and returns normalized values in both formats.
Unix timestamp questions
What is a Unix timestamp?
A Unix timestamp counts elapsed seconds since January 1, 1970 at 00:00:00 UTC. Some systems store the same value in milliseconds.
Does the converter support milliseconds?
Yes. OmniKit automatically treats values with an absolute size of 100 billion or more as milliseconds and smaller values as seconds.
Why is local time different from UTC?
Local time applies the time zone configured on your device, while ISO output is shown in UTC.
