title: Does 'timer' take more CPU power?
body: <p>I've used timer and I found it very helpful while taking decisions in seconds or milliseconds.
  Now I have strong feelings that continuous running of timer gradually increases consumption of processor cycles.</p>
  
  <p>I've created an application (C#) and used 'timer tick' to execute 'three' instructions per 1000 milliseconds (1 sec) and I noticed that after 5 minutes application was consuming 5% of CPU power and 10% after 10 minutes.</p>
  
  <p>If this progress remains constant then what will happen after 4-5 hours if I run my application in background?</p>
  
  <p>Should I avoid excessive use of timer?</p>
  
  <pre><code>private void currentTime_Tick(object sender, EventArgs e)
  {
     label1.Text = DateTime.Now.ToString("HH:mm:ss tt");
     label2.Text = dt.AddSeconds(i).ToString("HH:mm:ss");
     i++;
  }
  </code></pre>
