In terms of performance, yes, but in terms of power, no. If NTP gets the CPU out of a deep stand-by state, then it may take hundreds of milliseconds for the CPU to go back to that state. Moreover, NTP 1s- timer may prevent the CPU from going to even deeper stand-by states. With this in mind, if NTP wakes the CPU up in order to do nothing, it's not doing the right thing, IMHO.
