title: How to compare two datetimes
body: <p>I wonder how to compare two DateTime objects in .NET using DateTime methods <code>Compare</code>, <code>CompareTo</code> or <code>Equals</code> without comparing ticks. </p>
  
  <p>I only need a tolerance level of milliseconds or seconds.</p>
  
  <p>How can this be done?</p>
