Unix Time Converter
Unix Time Converter shows the current Unix timestamp ticking live and converts epoch seconds to a human date — in your local zone, UTC and ISO 8601 — and back again.
It is the quickest way to grab 'now' as an epoch value or to decode one you found in a log or database. Everything runs in your browser.
How to use Unix Time Converter
- 1
Read the live clock
The current Unix timestamp updates every second; copy it or click Convert this.
- 2
Convert seconds to a date
Enter epoch seconds to see the local, UTC, ISO and relative rendering.
- 3
Convert a date to seconds
Pick a date and time to get its Unix timestamp.
What is Unix time?
Unix time, also called epoch time or POSIX time, is the number of seconds that have elapsed since midnight UTC on 1 January 1970, not counting leap seconds. Because it is a single integer in UTC, it is unambiguous and easy to store, compare and sort, which is why it underpins so much of computing.
Today's values are ten digits; they will become eleven digits in the year 2286.
Why epoch seconds are everywhere
Databases, log files, JWT tokens, HTTP headers and APIs commonly express time as epoch seconds. Converting to a readable date makes those values human-friendly, and converting back lets you craft a value to paste into a query or request.
If your value has thirteen digits it is in milliseconds — the Timestamp Converter handles every unit automatically.
Frequently asked questions
- Is the current time accurate?
- It reads your device clock and ticks once per second, so it is as accurate as your computer's time.
- Does this use seconds or milliseconds?
- This tool is centred on epoch seconds. For milliseconds and microseconds, use the Timestamp Converter, which auto-detects the unit.
- Is my data uploaded?
- No. The conversion runs entirely in your browser.
