알아둘 점
Auto Detect uses a numeric range heuristic: values up to 100 billion are treated as seconds and larger values as milliseconds when both fit the JavaScript date range. Choose a unit explicitly for unusual historical or far-future values.
자주 묻는 질문
What is the current Unix timestamp?
The live clock at the top of this page shows the current Unix timestamp in seconds and milliseconds and updates every second.
Is Unix time measured in seconds or milliseconds?
The original Unix time convention counts seconds since 1970-01-01 00:00:00 UTC. Many JavaScript APIs use milliseconds, so this tool supports both.
Does Unix time use UTC?
Yes. Unix timestamps represent an instant relative to UTC and do not contain a time-zone name. The same value can be displayed in local time or any IANA time zone.
How can I tell if a timestamp is seconds or milliseconds?
Common current seconds values are around 1.7 billion, while current milliseconds values are around 1.7 trillion. Auto Detect uses a numeric range rule; select Seconds or Milliseconds when you know the source.
Can Unix timestamps represent dates before 1970?
Yes. Negative values represent instants before the Unix epoch. For example, -1 second is 1969-12-31 23:59:59 UTC.
Is my data uploaded to a server?
No. Dates, times and timestamps are calculated locally in your browser and are never uploaded to a server.
