Frequently Asked Questions

What is Unix time (Epoch)?

Unix time is a system for describing a point in time, defined as the number of seconds that have elapsed since 00:00:00 UTC, 1 January 1970.

Why use seconds vs milliseconds?

Unix timestamps are traditionally in seconds. However, high-precision applications and JavaScript's Date object use milliseconds (13 digits instead of 10).

Does this work with my timezone?

Yes! You can select any timezone from the settings. The converter uses the comprehensive IANA timezone database for precise localization.

Is my data secure?

Absolutely. All conversions are performed entirely on your device (client-side) using JavaScript. No date or time data ever leaves your browser.

What is the maximum date?

Standard 32-bit unix timestamps will overflow in 2038. However, this tool uses 64-bit numbers and supports dates far into the future.

What is ISO 8601 format?

ISO 8601 is the international standard for date and time representation (e.g., YYYY-MM-DD HH:MM:SS), which we support in the results.

How do I get the current timestamp?

Simply click the Set Now button to instantly fill the input fields with the current time.

What is the Year 2038 problem?

It is a computing issue where 32-bit systems will run out of seconds to represent time after January 19, 2038. 64-bit systems are not affected.

Can I copy the result?

Yes, click the copy icon next to any result field to copy the formatted date or timestamp to your clipboard.

Does it support negative timestamps?

Yes, negative timestamps represent dates before the Unix Epoch (Jan 1, 1970).
