Timestamp Converter
Convert a Unix timestamp (seconds) to a readable UTC and local date, or build a timestamp from a date. Great for debugging logs and APIs.
Frequently asked questions
Seconds or milliseconds?
This tool uses seconds (the standard Unix timestamp). If you have milliseconds, divide by 1000 first — or note the ms value shown alongside.
Why are there UTC and local times?
A timestamp is absolute; how it reads depends on your timezone. Both are shown so you never misread a log entry.
Is anything uploaded?
No. All conversions happen in your browser using the local clock.
