MCP server-time does not work on non-English system

[kurtthomas]

Describe the bug
Thank you for server-time.

Attempting to run the server-time MCP fails on a system where time zone names are not in English.

To Reproduce
Steps to reproduce the behavior:

1. Be on a Windows system where English is not the primary OS language.
2. Set local Windows time zone to (name of MET in local language).
   Either:
   3A Start Claud AI Desktop Agent ==> Cannot connect to MCP server.
   /Or/
   3A Start mcp-server time with uvx ==> Error (see below)

Expected behavior
MCP works.

Logs
uvx command:
uvx mcp-server-time
Command error output:
Traceback (most recent call last):
File "C:\Users\Kurt\AppData\Local\Programs\Python\Python311\Lib\zoneinfo_common.py", line 12, in load_tzdata

(Emphasis added)

Additional context
Mitteleuropäische Zeit is the German / Windows name for "MET".
Workaround is to find the MET file and copy it to .

This seems like it might be a bug in Python's zoneinfo module, as the server doesn't do this part itself.

still the issue, having the same trouble but in my case i'm using

"time": { "command": "uvx", "args": [ "mcp_server_time" ] },
