datetime-mcp

Implementation Reference

• src/server.ts:101-106 (handler)

  The registration and handler implementation for the 'datetime.health' tool. It calls 'healthPayload' and returns its result.

  server.tool("datetime.health", {}, async () => {
    const payload = healthPayload();
    return {
      content: [{ type: "text", text: JSON.stringify(payload, null, 2) }],
    };
  });

• src/server.ts:71-78 (helper)

  Helper function that generates the payload for the health check.

  function healthPayload() {
    // Monotonic time (won't jump backwards/forwards with NTP clock changes)
    const monotonicMs = Number(process.hrtime.bigint() / 1_000_000n);
    const wallEpochMs = Date.now();
    const processUptimeMs = Math.round(process.uptime() * 1000);
  
    return { wallEpochMs, monotonicMs, processUptimeMs };
  }
