Time Intelligence Agent

Timely is a time-focused A2A agent combining deterministic time tools with LLM-powered time chat. It handles date arithmetic, timezone conversion, and scheduling queries—computation that language models get wrong on their own.

Why Timely?

LLMs don't have clocks. They hallucinate dates, miscalculate “next Tuesday,” and ignore correct API responses in favor of “mental” reasoning. Timely solves this with deterministic time tools that return authoritative answers computed from the system clock—no generation, no hallucination.

“I've been trying to ‘mentally calculate’ which day of the week each date falls on. Even though the API is telling me what the date of week is, I should probably trust it.”— An LLM agent that scheduled every event on the wrong day
