Does our current implementation of ntp_gettime() make any sense?
On first glance it looks like a compatibility kludge for an ancient
version of struct ntptimeval only found on FreeBSD 3.x.
On more careful inspection, I notice that it doesn't even work!
$ cat ntp_gettime.c
#include <unistd.h>
#include <sys/timespec.h>
#include <sys/timex.h>
#include <stdio.h>
int
main ()
{
struct ntptimeval tv;
ntp_gettime (&tv);
printf ("%ld\n", tv.time);
}
$ gcc ntp_gettime.c && ./a.out

But there is a ntp_gettime syscall now. Should we just replace this code
with a direct syscall stub?
$ cat syscall.c
#include <unistd.h>
#include <sys/timespec.h>
#include <sys/timex.h>
#include <sys/syscall.h>
#include <stdio.h>
int
main ()
{
struct ntptimeval tv;
syscall (SYS_ntp_gettime, &tv);
printf ("%ld\n", tv.time);
}
$ gcc syscall.c && ./a.out
