Question 1

What is a Unix timestamp?

Accepted Answer

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is widely used in programming, databases, and APIs to represent dates and times as a single integer value.

Question 2

Does this tool detect millisecond timestamps automatically?

Accepted Answer

Yes. The converter automatically detects whether your input is in seconds (10 digits) or milliseconds (13 digits) and converts accordingly. Both formats are shown in the output results for easy reference.

Question 3

What date formats does the timestamp converter output?

Accepted Answer

The tool outputs dates in ISO 8601, RFC 2822, localized long format, short date/time format, relative time (e.g., '3 days ago'), and both seconds and milliseconds representations. It also shows the day of the year.
