title: Convert Date to Milliseconds
body: <p>I am working with Visual Studio 2010, MVC 3 and C#.  I am creating some highcharts and need to have the x-axis be a date.  I am pulling the dates from a database and adding them to and array that will then be passed to highcharts.  I think highcharts requires the dates to be in millisecond format.  Ho do I go about converting a DateTime of '12/20/2011 5:10:13 PM" for example to milliseconds?</p>
