A wireless communication device includes an applications processor to operate
one
or more personal information management (PIM) applications. Upon initial registration
or when transiting to a new location, a baseband processor of the device automatically
derives the local time using a time-zone database and current location information
received from the communication network. The PIM applications operating within
the device are updated with the local time. The device may receive location-based
services such as advertisements that depend on the current location.
