[time-nuts] Time syncing question

[Daun Yeagley]

CDMA phones have their clocks set by the system, as they require more precise
synchronization of not only the data stream bit timing, but also the
synchronization of the psuedo random key streams. These are used for syncing up
the Walsh codes as well as security encryption key functions.

I have observed that some cell phones set their clock when you power them up,
and others set it at regular time. Some automatically change time zone as you
travel and some don't, maybe due to the same process.
