title: Powershell ConvertToJson date serialization
body: <p>I am running into date issues when serializing to json from Powershell using the ConverTo-Json commandlet.</p>
  
  <p>It generates dates that look like this:</p>
  
  <pre><code>"\/Date(1476684000000)\/"
  </code></pre>
  
  <p>I need it to generate a date with an offset that looks like:</p>
  
  <pre><code>"\/Date(1476684000000-0600)\/"
  </code></pre>
  
  <p>I can't seem to find anything in the docs that allows me to specify this.  Do I need to do this myself by hand?</p>
