title: Binding single datevalue to DatePicker and TimePicker
body: <p>sap.m.DateTimeInput is deprecated, the doco suggests using sap.m.DatePicker and sap.m.TimePicker instead</p>
  
  <blockquote>
    <p>Deprecated since version 1.32.8. Instead, dedicated sap.m.DatePicker
    and/or sap.m.TimePicker controls should be used.</p>
  </blockquote>
  
  <p>I can bind a single datevalue to both controls</p>
  
  <pre><code>&lt;Label text="Start Date" /&gt;
  &lt;HBox class="sapUiSmallMarginBottom"&gt;
      &lt;DatePicker dateValue="{VM&gt;/StartDate}" displayFormat="dd/MM/yyyy"&gt;
          &lt;layoutData&gt;
              &lt;FlexItemData growFactor="1" /&gt;
          &lt;/layoutData&gt;
      &lt;/DatePicker&gt;
      &lt;TimePicker dateValue="{'VM&gt;/StartDate'}" width="100%" &gt;
          &lt;layoutData&gt;
              &lt;FlexItemData growFactor="1" /&gt;
          &lt;/layoutData&gt;
      &lt;/TimePicker&gt;
  &lt;/HBox&gt;
  </code></pre>
  
  <p>however when i change the TimePicker, the date is set to epoch and similarly when i change the DatePicker the time value is reset.</p>
  
  <p>I want to be able change the DatePicker and keep the TimePicker value and similarly change the TimePicker and keep the DatePicker value. </p>
  
  <p>Anyone know how to do this, the only event is change and this appears to be too late.</p>
