While there is the facility to get the time from the masts since at least GPRS days, in practice I found too many masts with wrongly set times to make it of any use. Maybe these days it's better, but at the same time you can get sub-second accurate times either over NTP over IP or from the GPS time signals, which are magnitudes more reliably in my experience.
Really? How does a phone handle this? The advantage is, its working automatically immediately when the modem is switched on, without internet and gps. Also it recognizes the timezone change on travelling.
