Comment 6 for bug 43233

The sudo man page says that -k and -K should reset the timestamp. If that's not really what they do, could the man page be updated to describe their actual functions? (What do they really do?)

Since this is something that seems to happen pretty commonly during the edgy install process (comments in the two bugs here, plus lots of google hits), it would be really useful to have a way of doing what the man page says -k/-K do: reset the timestamp now, so that the next call to sudo will prompt for a password. Currently, once it gets into this state there's no way of getting out, unless you have some other way of resettting the system clock; sudo just keeps repeating the error message and -k and -K don't fix it.
