agent: mcp

When does this happen?

IF MCP time server fails with ZoneInfoNotFoundError when local timezone is set to an abbreviation like EDT, PDT, CST, or BST.

How others solved it

THEN Set the --local-timezone argument to a valid IANA timezone identifier (e.g., 'America/New_York') instead of an abbreviation. If using a system that provides abbreviations, map them to IANA keys or install the tzdata package with proper zoneinfo files. Alternatively, the server code should be updated to handle abbreviations by converting to IANA keys where possible.

uvx mcp-server-time --local-timezone "America/New_York"
