>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 ?
