Convert Unix time, ISO, and Discord timestamps

Logs, APIs, databases, and metadata store time as Unix epoch seconds or milliseconds; investigators and developers constantly need to translate those into readable dates and back. This converter detects the input automatically and outputs every format you are likely to need, including Discord’s dynamic timestamp tags and Windows FILETIME.

Frequently asked questions

What's the difference between Unix seconds and milliseconds?

Unix time counts from 1 January 1970 UTC. Seconds-based timestamps are 10 digits; millisecond timestamps are 13. This tool detects which you pasted and converts accordingly.

Can it generate Discord timestamps?

Yes. It outputs Discord’s tags (short and relative) that render as live, timezone-aware times in Discord messages.

What is Windows FILETIME?

FILETIME counts 100-nanosecond intervals since 1 January 1601 UTC and appears in Windows artifacts and forensic data. The tool converts your date to and from it.

Does it work offline / is anything sent anywhere?

All conversion is pure JavaScript in your browser. Nothing is sent to any server.
