About the Timestamp Converter
The Timestamp Converter translates Unix timestamps into human-readable dates and converts dates back into Unix time, handling both seconds and milliseconds. It is invaluable for debugging logs, API responses and database records that store time as raw numbers. The conversion runs in your browser, so your data stays on your machine.
How to use
- Paste a Unix timestamp or pick a date.
- Choose seconds or milliseconds if needed.
- Read the converted date or timestamp.
- Copy the result into your logs, query or code.
Frequently asked questions
- What is a Unix timestamp?
- A Unix timestamp is the number of seconds (or milliseconds) elapsed since midnight UTC on January 1, 1970, known as the epoch. It is a compact, timezone-independent way to represent a moment in time.
- How do I know if a timestamp is in seconds or milliseconds?
- A seconds-based timestamp for a recent date is about 10 digits, while a milliseconds-based one is about 13 digits. The converter lets you choose the unit to interpret it correctly.
- Does the converter handle time zones?
- Unix time is always UTC. The tool can show the equivalent UTC and local time so you can reconcile values across systems.
