Detailed Description

Precision Time Protocol time specification.

Function Documentation

net_ptp_time_to_ns()

static net_time_t net_ptp_time_to_ns ( struct net_ptp_time *  ts )

inlinestatic

#include <zephyr/net/ptp_time.h>

Convert a PTP timestamp to a nanosecond precision timestamp, both related to the local network reference clock.

Note

Only timestamps representing up to ~290 years can be converted to nanosecond timestamps. Larger timestamps will return the maximum representable nanosecond precision timestamp.

Parameters

ts	the PTP timestamp

Returns

the corresponding nanosecond precision timestamp

ns_to_net_ptp_time()

static struct net_ptp_time ns_to_net_ptp_time ( net_time_t  nsec )

inlinestatic

#include <zephyr/net/ptp_time.h>

Convert a nanosecond precision timestamp to a PTP timestamp, both related to the local network reference clock.

Parameters

nsec	a nanosecond precision timestamp

Returns

the corresponding PTP timestamp
