About this tool

This epoch converter is useful for logs, JWT claim inspection, and incident investigations. It quickly translates raw UNIX times into readable UTC/local timestamps and back.

Common use cases

  • Translate auth token times (exp/iat/nbf).
  • Debug SIEM and application log timestamps.
  • Convert human dates for scripts and API calls.

How it works

  1. Enter epoch or datetime.
  2. Run the desired conversion.
  3. Copy UTC/local/seconds/ms output.

FAQ

Seconds vs milliseconds?
Both are supported. Large values are treated as milliseconds.

Does this use my timezone?
Yes, local output uses your browser timezone.
