What make/model? This is interesting. I have seen something like this before. It might work tomorrow. It might take one 2 AM transition. Or it might work in another hour when 11-Mar-2007 UTC is over. Can you try it again a few times and tell me when it first comes up with the correct time? If so, it's another untested bug in RC clock firmware. Read the WWVB docs and note the two DST bits (57 and 58) are quite tricky on the day of the switchover, especially considering the difference between the UTC day and the local day, when the reception is made vs. when the clock needs to (or needed to) be advanced.
