FAQ
Frequently Asked Questions
- Is this client-side only?
- Yes. All timestamp conversion uses JavaScript's Date object in your browser. Nothing is sent to a server.
- What is a Unix timestamp?
- A Unix timestamp is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (the Unix epoch). It is a standard way to represent a point in time in computing.
- Does this support millisecond timestamps?
- Yes. The tool detects whether the input is a standard Unix timestamp in seconds or a millisecond timestamp and converts accordingly.
- Why does my timestamp convert to the wrong date?
- Verify whether you have a seconds-based or millisecond-based timestamp. A 13-digit number is typically milliseconds; a 10-digit number is typically seconds.
