About Timestamp
Unix timestamps count seconds since the start of 1970. They are compact and unambiguous for machines, and unreadable for people, so converting between the two is a routine debugging task.
How to use it
- Enter a timestamp, or pick a date and time.
- Convert in the direction you need.
- Copy the result.
Worth knowing
Check whether your value is in seconds or milliseconds — a millisecond timestamp read as seconds lands tens of thousands of years in the future, which is the classic symptom.
Common questions
- Which timezone applies?
- Unix time is UTC by definition. The offset is applied when it is displayed, which is where most confusion starts.
- Why is my date in 1970?
- A zero or empty value converts to the epoch itself — usually a missing field rather than a real date.
