Supports hardware and software time stamping via the Linux SO_TIMESTAMPING socket option. Supports the Linux PTP Hardware Clock (PHC) subsystem by using the clock_gettime family of calls, including the clock_adjtimex system call. Implements Boundary Clock (BC), Ordinary Clock (OC) and Transparent Clock (TC).
https://en.wikipedia.org/wiki/Precision_Time_Protocol
The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network.On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. PTP is currently employed to synchronize financial transactions, mobile phone tower transmissions, sub-sea acoustic arrays, and networks that require ...

In the last days I was working at Centricular on adding PTP clock support to GStreamer. This is now mostly done, and the results of this work are public but not yet merged into the GStreamer code base. This will need some further testing and code review, see the related bug report here.

Linux is becoming the leading operating system for embedded devices, but little attention has been paid to the issue of how to internally synchronize the Linux system clock with the PTP hardware ...

-S gets the time stamps in software in the Linux networking stack. > What hardware support is needed for option -S? No special HW support is needed. > Is it a driver problem? Yes. The receive time stamp is handled by the core networking code, but the transmit time stamp must be done in the driver. Many, but not all drivers implement it.

Unicast in addition to multicast support: When PTP was first introduced, it only specified support for multicast message exchanges between PTP clock sources and clients. However, in the telecom environment, unicast support is required in order to fine-tune and optimize network performance. With multicast, every device in the multicast group

This patch set introduces support for IEEE 1588 PTP clocks in Linux. Together with the SO_TIMESTAMPING socket options, this presents a standardized method for developing PTP user space programs, synchronizing Linux with external clocks, and using the ancillary features of PTP hardware clocks.
