There is a thread on http://tech.groups.yahoo.com/group/FMT-nuts/ with many observations of WWV reporting the wrong time. Here is a clip of just one of them:

I was able to verify this by listening to WWV and comparing the time announcements with my GPS-DO. The time was not consistently announced wrong -- just every few minutes (like above). I am sorry I didn't keep a better log of the exact time and frequency where I heard this. I just assumed that since so many guys were reporting the same thing that the WWV staff would know about it. I was surprised when they didn't.
