A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC), not counting leap seconds. It's also known as POSIX time or epoch time.

What's the difference between seconds and milliseconds timestamps?

Seconds timestamps count in whole seconds since the Unix epoch, while milliseconds timestamps count in milliseconds (thousandths of a second). JavaScript typically uses milliseconds, while many Unix systems use seconds.

What timezones are supported?

The tool supports all major timezones including UTC, EST, PST, CET, and many others. You can select from a comprehensive list of timezones to convert your timestamp to local time anywhere in the world.

What date formats are available?

You can choose from multiple formats including ISO 8601 (2023-12-25T14:30:00), RFC 2822 (Mon, 25 Dec 2023 14:30:00 GMT), human readable (December 25, 2023 2:30 PM), and custom formats with day, month, year, hour, minute, and second components.

Does this tool work with negative timestamps?

Yes, the converter supports negative timestamps which represent dates before January 1, 1970. This allows you to convert historical dates to timestamps and vice versa.
