    <summary>Core timekeeping facilities.</summary>
    <remarks>
      <para>Core timekeeping facilities.</para>
      <para>Three different clocks are available, and they should not be confused:
            
            &lt;ul&gt;
                &lt;li&gt;</para>
      <para>
        <c>System#currentTimeMillis System.currentTimeMillis()</c>
                is the standard "wall" clock (time and date) expressing milliseconds
                since the epoch.  The wall clock can be set by the user or the phone
                network (see <c>#setCurrentTimeMillis</c>), so the time may jump
                backwards or forwards unpredictably.  This clock should only be used
                when correspondence with real-world dates and times is important, such
                as in a calendar or alarm clock application.  Interval or elapsed
                time measurements should use a different clock.  If you are using
                System.currentTimeMillis(), consider listening to the
                <c>android.content.Intent#ACTION_TIME_TICK ACTION_TIME_TICK</c>,
                <c>android.content.Intent#ACTION_TIME_CHANGED ACTION_TIME_CHANGED</c>
                and <c>android.content.Intent#ACTION_TIMEZONE_CHANGED
                ACTION_TIMEZONE_CHANGED</c><c>android.content.Intent Intent</c>
                broadcasts to find out when the time changes.
            
                &lt;li&gt;</para>
      <para>
        <c>#uptimeMillis</c> is counted in milliseconds since the
                system was booted.  This clock stops when the system enters deep
                sleep (CPU off, display dark, device waiting for external input),
                but is not affected by clock scaling, idle, or other power saving
                mechanisms.  This is the basis for most interval timing
                such as <c>Thread#sleep(long) Thread.sleep(millls)</c>,
                <c>Object#wait(long) Object.wait(millis)</c>, and
                <c>System#nanoTime System.nanoTime()</c>.  This clock is guaranteed
                to be monotonic, and is suitable for interval timing when the
                interval does not span device sleep.  Most methods that accept a
                timestamp value currently expect the <c>#uptimeMillis</c> clock.
            
                &lt;li&gt;</para>
      <para>
        <c>#elapsedRealtime</c> and <c>#elapsedRealtimeNanos</c>
                return the time since the system was booted, and include deep sleep.
                This clock is guaranteed to be monotonic, and continues to tick even
                when the CPU is in power saving modes, so is the recommend basis
                for general purpose interval timing.
            
            &lt;/ul&gt;
            
            There are several mechanisms for controlling the timing of events:
            
            &lt;ul&gt;
                &lt;li&gt;</para>
      <para>Standard functions like <c>Thread#sleep(long)
                Thread.sleep(millis)</c> and <c>Object#wait(long) Object.wait(millis)</c>
                are always available.  These functions use the <c>#uptimeMillis</c>
                clock; if the device enters sleep, the remainder of the time will be
                postponed until the device wakes up.  These synchronous functions may
                be interrupted with <c>Thread#interrupt Thread.interrupt()</c>, and
                you must handle <c>InterruptedException</c>.
            
                &lt;li&gt;</para>
      <para>
        <c>#sleep SystemClock.sleep(millis)</c> is a utility function
                very similar to <c>Thread#sleep(long) Thread.sleep(millis)</c>, but it
                ignores <c>InterruptedException</c>.  Use this function for delays if
                you do not use <c>Thread#interrupt Thread.interrupt()</c>, as it will
                preserve the interrupted state of the thread.
            
                &lt;li&gt;</para>
      <para>The <c>android.os.Handler</c> class can schedule asynchronous
                callbacks at an absolute or relative time.  Handler objects also use the
                <c>#uptimeMillis</c> clock, and require an <c>android.os.Looper
                event loop</c> (normally present in any GUI application).
            
                &lt;li&gt;</para>
      <para>The <c>android.app.AlarmManager</c> can trigger one-time or
                recurring events which occur even when the device is in deep sleep
                or your application is not running.  Events may be scheduled with your
                choice of <c>java.lang.System#currentTimeMillis</c> (RTC) or
                <c>#elapsedRealtime</c> (ELAPSED_REALTIME), and cause an
                <c>android.content.Intent</c> broadcast when they occur.
            &lt;/ul&gt;</para>

            synchronized using a remote network source outside the device.</para>
          <para>While the time returned by <c>System#currentTimeMillis()</c> can be
            adjusted by the user, the time returned by this method cannot be adjusted
            by the user.</para>
          <para>This performs no blocking network operations and returns values based on
            a recent successful synchronization event; it will either return a valid
            time or throw.</para>
          <para>Note that synchronization may occur using an insecure network protocol,
            so the returned time should not be used for security purposes.
            The device may resynchronize with the same or different network source
            at any time. Due to network delays, variations between servers, or local
            (client side) clock drift, the accuracy of the returned times cannot be
            guaranteed. In extreme cases, consecutive calls to <c>Clock#millis()</c> on the returned <c>Clock</c>could return times that are
