ptp_time.h File Reference

Detailed Description

High-precision "Time" object for use with PTP / IEEE1588.

This file defines the satcat5::ptp::Time object, which is a high-precision timestamp intended for use with the IEEE1588 Precision Time Protocol (PTP).

For simpler but less precise timestamps,
