title: Setting Parameter Default value to a Date/Time
body: <p>I have an SSRS report built in Visual Studio 2017.
  There is a start and end date. The start being -1 week from todays date at 6am, and the end date being todays date at 5:59am.</p>
  
  <p>I'd normally set these values in SQL, but someones requested the ability to select the date range using parameter drop downs as well. </p>
  
  <p>I opened up the parameter in VS, went to default values and then not knowing Visual Basic didn't know the next step.</p>
