Just to revisit this - I actually bought an "automatic setting" clock now that I saw one at Walmart.
Unfortunately, Sharp is lying. "Accu-Set(tm)" is them factory-programming the clock IC and just shipping a button cell in the box and hoping it holds time. My clock was 5 minutes behind and I have to manually set it. No RDS, no radiotime, nothing.
Oi... guess I have to be even more specific in my product hunt.
