Comment 34 for bug 43233

This has been a problem on my server at work.
It turned out that a hard drive was corrupting the hwclock. I don't know how it was doing this but every time the machine rebooted with the hd connected the date in cmos would reset to 00/1/1983. With the any other drive in its place it works fine.
The issue with sudo -K not working is very annoying because the server only gets reset when I am doing some sort of maintenance where I will need to use sudo.

It seems that the only way I can use sudo -K is to open another tty. If this is by design, then shouldn't the man page be revised?
