Well, it is a phone... It's going to have access to geo data from the local cell phone towers, no timezone hacks necessary. In fact I believe the iPhone adjusts your active timezone automatically according to the geo data collected from the local cell tower, hence why your phone time changes when you touch down after a long flight.
- eigenvector 12y agoActually the time update is not based on inference from location data, but rather it is actively transmitted by the cell network as part of the GSM standard. http://en.wikipedia.org/wiki/NITZ http://en.wikipedia.org/wiki/NITZ
- BuildTheRobots 12y agoThough it's possibly worth pointing out that time/date is not a _requirement_ to the standard and not all networks implement it. It's possibly also worth pointing out that most recent Android devices seem to use NTP at the OS level rather than relying on GSM broadcast info.
- lucaspiller 12y agoAs the other poster said, time has it's own standard. In terms of your reply to OP, it's even simpler. The network identifier for an operator broadcast by the cell tower consists of a network code and a country code :)
