[time-nuts] iPhone keeping better time?

I doubt we will ever see good time keeping on an IOS type device.  The
problem is battery life.  Good time keeping requires a  stable local
oscillator of some kind that must remain powered up 24x7.   But to get
the long battery life they must power off everything they possibly
can.  No mater how far technology advances it will always require less
power to not ruin an oscillator then to run one.

I doubt Apple would run NTP in an iPhone.  They don't want to multi
task the CPU and there is no stable  local oscillator to be
disciplined.
