What is a Unix timestamp?
A Unix (or “epoch”) timestamp is the number of seconds since midnight UTC on 1 January 1970. It’s how computers store a moment in time as a single number, free of time zones and date formats. Logs, APIs, databases and cookies are full of them.
Seconds or milliseconds?
Classic Unix time is in seconds (10 digits today). JavaScript and many APIs use milliseconds (13 digits). This tool auto-detects which you’ve pasted, or you can force it. We also show the time in Australian Eastern, which automatically accounts for daylight saving (AEST/AEDT).
