[time-nuts] iPhone keeping better time?

[Robin Kimberley]

I'm currently using a Samsung Galaxy S II, which I'm very impressed with.
Have just found an NTP client on the Android Market which seems to work OK. 

Will investigate further.

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.
