Detailed Description

Generalized Precision Time Protocol Extended Timestamp format.

This structure represents an extended timestamp according to the Generalized Precision Time Protocol standard (IEEE 802.1AS), see section 6.4.3.5.

Seconds are encoded as 48 bits unsigned integer. Fractional nanoseconds are encoded as 48 bits, their unit is 2*(-16) ns.

A precise definition of PTP timestamps and their uses in Zephyr is given in the description of net_ptp_time.
