mcp-simple-timeserver

Overview

The mcp-simple-timeserver is a well-designed MCP server that addresses Claude's lack of timestamp functionality. It provides multiple tools for time-related operations, including getting local time, UTC time from NTP servers, calculating time distances between dates, and checking holidays worldwide. The server supports multiple locations, timezones, and calendar systems including Japanese, Hebrew, Hijri, and Persian calendars. The documentation is comprehensive with clear examples and configuration instructions for both manual and Smithery installations.

FAQ

Does this work with other AI assistants besides Claude?

Yes, this is a standard MCP server that should work with any MCP-compatible client.

How accurate is the time information provided?

All tools except get_local_time use accurate time from NTP servers. If NTP is unavailable, they fall back to local server time with a notice.
