Specification
WHAT IS
TIMESTAMP CONVERTER?
Timestamp Converter parses Unix timestamps in seconds or milliseconds, plus ISO and browser-readable date strings, then shows the equivalent UTC, ISO, and local-time formats. It is useful when debugging APIs, logs, JWT claims, and scheduled jobs.
When to use it
- →Checking exp and iat values from JWT payloads
- →Converting log timestamps into local time during incident debugging
- →Verifying scheduled job times across UTC and local zones
- →Turning a human-readable date into epoch milliseconds for scripts and tests
Key Features
- ·Accepts Unix seconds, Unix milliseconds, ISO strings, and standard date strings
- ·Shows UTC, ISO 8601, local date/time, and raw Unix outputs together
- ·One-click copy for every output format
- ·Runs completely client-side in the browser with no backend calls
Privacy & Security Guarantee
WHY IN-BROWSER PROCESSING MATTERS FOR DEVELOPERS
Many online formatters and decoders send your code, JSON payloads, auth tokens, and database schemas to backend servers where they can be cached, logged, or intercepted. ToolBox4Devs guarantees that all processing for Timestamp Converter runs entirely in your browser's JavaScript V8 engine.
