Question 1

What is a Unix timestamp?

Accepted Answer

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch). It's commonly used in programming and databases to represent dates and times.

Question 2

How do I convert a Unix timestamp to a date?

Accepted Answer

Enter the Unix timestamp in the converter tool, select the unit (seconds or milliseconds), choose your timezone, and click convert. The tool will show the date in multiple formats including local time, RFC 2822, ISO 8601, and RFC 3339.

Question 3

What's the difference between seconds and milliseconds?

Accepted Answer

Seconds timestamps are 10 digits (e.g., 1704240000), while milliseconds timestamps are 13 digits (e.g., 1704240000000). Milliseconds provide more precision for applications that need sub-second accuracy.
