Control over app behavior also means that the appmust use the mobile
device's system time for its authoritative time source. Synchronizing
with authorized timing sources enables an app to perform a
number of important back-office functions that require synchronization
between the app, the device, the network, and the back office infrastructure.
Without this synchronization, a number of issues could arise
concerning control functions that must be accomplished in short time
frames, as well as the incorrect time-stamping of events.
