[arch-general] pacman-key complaining, but what to do about it?

[Magnus Therning]

On a newly set up system I've added the [haskell-core] repo [1], but
get stuck with the following message from `pacman`:

~~~~
% sudo pacman -Syy

I've read [2] and verified (to the best of my ability) that I have
correct time settings.  I've also tried resetting the keys, but that
doesn't improve the situation either.

What else could it be?  How do I find out?  What can I do about it?
