The PTPd daemon is an open source implementation for *nix system (e.g., Linux) of the IEEE 1588-2008 Precision Time Protocol (PTP) specification. It is a method by which a computer, communicating over a Local Area Network (LAN) can keep its local clock synchronized to a better time source, commonly referred to as a Master Clock.
