Control over app behavior also means that the app must 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.
