How to use this tool
What this tool does and how it can help.
A Unix timestamp (epoch time) is the number of seconds since 1970-01-01T00:00:00Z. It is commonly used in APIs, databases, log files, and message systems.
- Use timestamp → date conversion to inspect event times from logs and APIs.
- Use date → timestamp conversion for payloads and test fixtures.
- UTC timestamps are stable across time zones, while local time shows viewer-specific time.
All operations run directly in your browser. No backend or account is involved.
