timesync is a lightweight JavaScript library that lets browsers or Node.js clients keep a shared, accurate clock by synchronizing their local time with a single server or with multiple peers over HTTP, WebSockets, or WebRTC. It’s aimed at developers of real‑time apps (e.g., games, collaborative tools) who need a simple “master‑slave” or peer‑to‑peer time‑sync solution that provides a `now()` API and event hooks for offset changes.
