Use this tool from AI agents
This tool's engine is available to AI agents over MCP as convert_timezone. Add the Clean.tools server, then your agent can call it directly.

This converter turns a UTC time (UTC) into CET (Central Europe). For example, 9:00 AM UTC is 10:00:00 CET. The converter above is preset to UTC and CET, so you can pick any date and time and read the result, and it accounts for daylight saving automatically.
All conversions use your browser's built-in time zone database. Nothing is uploaded. No cost, no signup, no tracking.
Frequently asked questions
Does this handle daylight saving time?
Yes. UTC and CET shift with daylight saving in most regions, and the converter uses the correct offset for the specific date you choose rather than a fixed number of hours.
Can I use this from the command line or an AI agent?
Yes. It is a REST endpoint at https://api.clean.tools/v1/convert_timezone and an MCP server you can add to Claude, Claude Code, or Cursor. The @clean-tools/mcp npm package runs it as a local stdio server.

Use Clean.tools from your AI agent
This tool is also convert_timezone on the Clean.tools MCP server — the same engine, callable by your AI agent directly. No key, no signup: requests are processed in memory and request contents are never stored.
