Technical Documentation & FAQ

RFC 2822 Converter (Single)

  • Section A: The Technical Deep Dive RFC 2822 is the legacy 'English' date format. You will see this in the Date: header of every email you receive. It includes the weekday and month name (e.g., Tue, 23 Dec 2025 09:00:00 +0000). While it looks friendly to humans, it is notoriously hard for machines to parse due to locale-specific month names. JOTO uses a standardized, locale-agnostic parser to turn these headers into modern machine-readable formats.

  • Section B: Email & Web Use Cases

    • SMTP Debugging: Checking the 'Sent' time in a raw email source to identify mail-server delays.

    • HTTP Header Inspection: Parsing the Last-Modified or Expires headers from a browser's network tab to debug caching issues.

  • Section C: The Anatomy of an Email Date Tue, 23 Dec 2025 09:00:00 +0000:

    • Weekday: Mandatory (must match the date).

    • Month: 3-letter abbreviation.

    • Offset: Always numerical (+0000 instead of Z).

  • Section D: FAQ

    • Q: Why does my date have (PST) at the end? A: RFC 2822 allows for optional comments in parentheses. JOTO safely ignores these during conversion.
