I am attaching a patch which will make time stamps without a day name
like <2011-10-12> work correctly.  Furthermore, pressing C-c C-c on
a time stamp will fill in or fix the day name.

However, I am not sure if this patch is complete, or if it
has side effects.  So it would be good if a few people could
apply it and test it during their daily work for a few weeks,
and then report problems in this thread.
