title: Convert Json date string to JavaScript date object
body: <p>I have the following JSON object which has a date field in the following format:</p>
  
  <pre><code>{
      "AlertDate": "\/Date(1277334000000+0100)\/",
      "Progress": 1,
      "ReviewPeriod": 12 
  }
  </code></pre>
  
  <p>I want to write a regular expression or a function to convert it to a javascript object so that it is in the form:</p>
  
  <pre><code>{
      "AlertDate": new Date(1277334000000),
      "Progress": 1,
      "ReviewPeriod": 12 
  }
  </code></pre>
  
  <p>The above date format fails validation in the JQuery parseJSON method.</p>
  
  <p>I would like to convert the 1277334000000+0100 into the correct number of milliseconds to create the correct date when eval is called after validation.</p>
  
  <p>Can anyone help me out with a good approach to solving this?</p>
