Unix Timestamp Converter
The Unix Timestamp Converter switches between Unix epoch time — the number of seconds since January 1, 1970 — and human-readable dates, in either direction. Developers use it to decode a timestamp found in a log file or database record, or to generate a timestamp for testing an API that expects epoch time.
The conversion is computed directly in your browser using standard date math, so no timestamp or date you enter is ever sent to a server for processing.
How to Use the Unix Timestamp Converter
- Open the Unix Timestamp Converter tool.
- Enter a Unix timestamp, or a date and time.
- The tool converts it to the other format automatically.
- Copy the converted value you need.
Frequently Asked Questions
Does this handle timestamps in seconds or milliseconds?
It's built to work with standard Unix timestamps in seconds, and typically detects millisecond-based timestamps too since they're a common variant in JavaScript and APIs.
How does the tool handle time zones?
Unix timestamps are always based on UTC, and the tool shows the corresponding date in your local browser time zone alongside the UTC value so you can compare both.
Is any date or timestamp data I enter logged or sent anywhere?
No, the conversion is a simple local calculation performed in your browser, with nothing transmitted to a server.
