About this tool
Timestamp Converter supports bidirectional conversion between Unix timestamps (seconds/milliseconds) and human-readable dates with timezone selection.
Common uses: debugging log timestamps, API time field conversion, cross-timezone calculations.
Frequently asked questions
What's the difference between seconds and milliseconds?
Unix timestamps are usually in seconds (10 digits), but JavaScript uses milliseconds (13 digits). The tool detects and converts both.
Does it use my local timezone?
Yes, dates are shown in your browser's timezone, and you can also read the UTC value.
What is a Unix timestamp?
It's the number of seconds since 00:00:00 UTC on 1 January 1970 — a timezone-independent way to represent a moment in time.
