When a scheduling agent needs to know the time difference between São Paulo and London on July 15th, the answer changes depending on DST. LLMs get DST wrong 100% of the time. This MCP uses Luxon with the full IANA timezone database.

The Superpowers

  • DST Aware: Calculates offsets at a specific moment, correctly handling all DST transitions worldwide.
  • Full IANA Database: Supports all 400+ IANA timezones (America/Sao_Paulo, Europe/London, Asia/Kolkata, etc.).
  • Bidirectional: Shows both the source and target local times plus the exact offset in hours and minutes.

get_timezone_offset

Pass two IANA timezone names (e.g. "America/Sao_Paulo", "Europe/London") and optionally an ISO 8601 datetime. The engine returns the exact offset in hours/minutes and whether each zone is in DST. Never calculate DST offsets yourself — you will get it wrong. Calculates the exact offset between two IANA timezones at a specific moment, respecting Daylight Saving Time (DST). Powered by Luxon
