>Description:
Just after very fast boot uptimealways shows more than 30 sec.
looking to src/usr/bin/w/w.c:
if (sysctl(mib, 2, &boottime, &size, NULL, 0) != -1 &&
boottime.tv_sec != 0) {
uptime = now - boottime.tv_sec;
uptime += 30;
====================== ^^^^^
days = uptime / 86400;
uptime %= 86400;
hrs = uptime / 3600;
uptime %= 3600;
mins = uptime / 60;
secs = uptime % 60;
(void)printf(" up");
why utility increases uptime on 30 seconds ??
Is any real reasons for it ?
>How-To-Repeat:
Boot and run uptime
