AG TIME is a free tool that instantly converts the Unix timestamps (epoch) you meet in development and debugging into human-readable dates, and dates back into timestamps. No installation or signup required.


It automatically detects seconds, milliseconds or microseconds from the number of digits, and you can also set the unit manually. Results show the date & time in your chosen timezone along with ISO 8601, RFC 2822, relative time, weekday and day of year — all at once.


The world clock on the home page shows live local time for major cities, and the World Clock page lets you check detailed time and UTC offset per city. The Guides explain concepts like the epoch, ISO 8601, daylight saving time and the Year 2038 problem.


All conversions run through the browser's Date and Intl APIs only. No input or result is ever sent to a server or stored.

What is a timestamp?

Unix timestamp

The number of seconds elapsed since January 1, 1970 00:00:00 UTC (the epoch). It is an absolute point in time independent of timezone, widely used in servers, logs and databases.

Seconds · ms · µs

The unit differs by language and system. JavaScript commonly uses milliseconds (13 digits) while Unix systems use seconds (10 digits). We auto-detect it from the digit count.

Timezones & UTC

The same timestamp shows a different clock time depending on the timezone. UTC is the reference, and you can check any region on the World Clock page.

In-browser processing

Every conversion runs on your device. Timestamps and dates are never sent to a server, so it's safe to use.

Frequently asked questions

What's the difference between a 10-digit and a 13-digit number?

A 10-digit number is usually a timestamp in seconds (Unix seconds), and 13 digits is in milliseconds (Unix milliseconds). AG TIME distinguishes them automatically from the digit count, and you can also pick the unit yourself.

Is my timestamp sent to a server?

No. All conversions run only through the browser's Date and Intl APIs, and no value is ever sent to a server or stored.

Can I view the time in another country?

Yes. Choose UTC or a major city timezone in the converter's timezone selector, or open the World Clock page, to display the time for that region. The default is your device's local time.

Is daylight saving time (DST) handled?

Yes. Times and offsets use the browser's Intl timezone data, so each region's daylight saving time is applied automatically.
