Timestamp converter. Epoch to human, both ways.
Turn any Unix epoch into a human date and back — Local, UTC and ISO 8601, relative time, and a live current timestamp. Auto-detects seconds, milliseconds, microseconds and nanoseconds. Computed on your device, nothing uploaded.

§ 02 · what you can do
Everything an engineer needs.
- Convert epoch to date: paste any Unix timestamp and see Local, UTC and ISO 8601 formats instantly.
- Convert date to epoch: pick a date and time to get the matching Unix timestamp in seconds and milliseconds.
- Auto-detect the unit: the tool recognises seconds, milliseconds, microseconds and nanoseconds by magnitude — no dropdown to fiddle with.
- See relative time: know at a glance whether a timestamp is “5 minutes ago” or “in 2 days”.
- Copy the live epoch: grab the current Unix time in seconds or milliseconds with one click.
- Use current time as input: press “Use as input” to pre-fill the epoch field with the present moment.
§ 03 · how to use it
Four steps, no manual.
- To convert an epoch to a date, paste your Unix timestamp into the left field — Local, UTC and ISO 8601 results appear instantly.
- To convert a date to an epoch, use the date & time picker on the right — the seconds and milliseconds values update as you change it.
- Read the relative-time chip to see how far in the past or future the moment falls.
- Click any copy button next to a result to put it on your clipboard in one click — or grab the live current epoch up top.
§ 04 · faq
Frequently asked questions.
Is the Timestamp Converter free?
Yes — completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Is my data sent anywhere?
No. The converter runs entirely in your browser on your own device — the timestamps you enter never leave your computer and nothing is uploaded to a server.
How does it tell seconds from milliseconds?
By digit count. A 10-digit value is read as seconds, 13 digits as milliseconds, 16 as microseconds and 19 as nanoseconds — the standard magnitudes for a present-day epoch. The panel shows which unit it detected.
Which time zone are the results in?
The “Local” row and the date picker use your device's own time zone, while UTC and ISO 8601 are shown alongside so you always have an unambiguous reference.
Does it work offline?
Yes — once the page has loaded, every conversion runs locally, so it keeps working without a connection.
