NtpClient class

A socket-based implementation of an NTP (Network Time Protocol) client.

This implementation communicates directly with an NTP server over UDP to retrieve the current UTC time. It is intended for platforms where raw sockets are available (e.g., mobile or desktop) and cannot be used in browser environments.

By default, it queries the public NTP pool (pool.ntp.org) on port 123, but the server, port, and timeout parameters can be customized via the constructor.
