I don't think the RTC frequency isn't the same as the timebase? Seems
like the RTC only case about seconds at the lowest level. If that's the
case then the jiffies clock might be better to use .. The other thing I
wonder is if the __USE_RTC boards might have lower level clocks that
could be used instead ..
