    14 <p> Time platform service provides the state of the device

    15 (mobile). It is controlled by a state machine that is SSM. These states

    16 are defined by system state policies within a SSM plug-in and system

    17 state changes are triggered by system-wide property changes or external

    18 requests. </p>

    22 of the functionality of Real Time Clock (RTC) adaptation interface. </p></li>

    23 <li><p>Alarm Server: manages all alarms on the device and enables

    24 client UI applications to use the services provided by the Alarm Server.

    25 It relies on the Alarm UI to notify, which includes displaying and

    26 playing sounds. </p></li>

    27 <li><p>Alarm Client and Alarm Shared: are the static interface DLLs.

    28 Alarm client is the client side of the Alarm Server, which allows

    29 other components to interact with the Alarm Server. The Alarm Shared

    30 facilitates a common format shared across server and its clients for

    31 providing definition for an alarm. It consists of shared objects such

    32 as alarm class, IPC messages, repeat definitions, alarm states. </p></li>

    33 <li><p>System State Manager (SSM): manages the state of a device throughout

    34 its lifecycle. SSM extends the existing Generic Start-up Architecture

    35 (GSA) and also manages the system state and the system-wide property.</p></li>
