Unix Timestamp Converter

Frequently asked questions

Seconds or milliseconds?

10-digit numbers are seconds (Unix), 13-digit are milliseconds (JavaScript Date.now()). DevTidy detects this from the length.

Is my data uploaded?

No. DevTidy runs entirely in your browser. Your input is processed on your device in a background Web Worker and never sent to a server, so it is safe for API keys, customer data and production configs.
