title: How to set DateTimePicker to certain time and keep the current date?
body: <p>When button is clicked, I want to set the <code>DateTimePicker</code> to show Date and Time as following:</p>
  
  <p><code>date</code> = current date.</p>
  
  <p><code>time</code> = <code>10:30:00</code>.</p>
  
  <p>The following code changes both date and time BUT does not keep current date:</p>
  
  <pre><code>private void button1_Click(object sender, EventArgs e)
  {
      dateTimePicker1.Value = new DateTime(2010, 1, 1, 10, 30, 0);
  }
  </code></pre>
  
  <p>What I want is : how to customize the time to <code>10:30:00</code> and keep the current date (today's date)?</p>
