Patent ID: 8161174

Claim:
A wireless system for deriving a time attribute of a device, the system comprising: a device-mode identifier configured to obtain a first time attribute based on a time set on the device, wherein the time set on the device is the device operating-system time; a device-location identifier configured to obtain through a mobile telecommunications network a second time attribute based on a time corresponding with a current location of the device, wherein the current location includes a location of a base station to which the device is connected via a cell tower associated with the base station; and a time attribute updater on the device configured to compare the first time attribute based on the time set on the device and the second time attribute based on the time corresponding with the current location of the device, wherein the time attribute updater determines whether the first time attribute based on the time set on the device and the second time attribute based on the time corresponding with the current location of the device differ, wherein when the time attribute updater determines that the first time attribute based on the time set on the device and the second time attribute obtained through the mobile telecommunications network that is based on the time corresponding with the current location of the device differ, and wherein when the base station is located in a first time zone and the device is located in a second time zone, then (A) notifying a user of a time attribute deviation by indicating that the time set on the device differs from the time corresponding with the current location of the device, (B) presenting an option to the user to select between accepting and declining a time attribute update, and (C) receiving a user selection to accept the time attribute update, wherein the time attribute updater communicates an update indication to an operating system of the device to modify the first time attribute based on the time set on the device to conform with the second time attribute based on the time corresponding with the current location of the device.
