This spec introduces support for a time synchronization
method called PTP (defined in the IEEE 1588-2008) which
provides better time accuracy than NTP in general. With
hardware timestamping support on the host, PTP can
achieve clock accuracy in the sub-microsecond range,
making it suitable for measurement and control systems.
