/*
|
|
||||||
* This header file defines the Network Time Protocol (NTP) interfaces
|
|
||||||
* for user and daemon application programs. These are implemented using

||||||
* defined syscalls and data structures and require specific kernel

|
|

*
|
|
||||||
* The original precision time kernels developed from 1993 have an
|

* ultimate resolution of one microsecond; however, the most recent
|
|
||||||
* kernels have an ultimate resolution of one nanosecond. In these

* kernels, a ntp_adjtime() syscalls can be used to determine which

* resolution is in use and to select either one at any time. The

* NAME
|
|

* ntp_gettime - NTP user application interface
|

*
|
|
||||||
* SYNOPSIS
|
|
||||||
* #include <sys/timex.h>
|
|
||||||
*
|
|
||||||
* int ntp_gettime(struct ntptimeval *ntv);
|
|
||||||
*
|
|
||||||
* DESCRIPTION
|
|
||||||
* The time returned by ntp_gettime() is in a timespec structure,
|
|
||||||
* but may be in either microsecond (seconds and microseconds) or
|
|
||||||
* nanosecond (seconds and nanoseconds) format. The particular
|
|
||||||
* format in use is determined by the STA_NANO bit of the status
|
|
||||||
* word returned by the ntp_adjtime() syscall.
|
|
||||||
*
|
|
||||||
* NAME
|
|
||||||
* ntp_adjtime - NTP daemon application interface
|
|
||||||

||||||
* SYNOPSIS

* #include <sys/timex.h>

*
