title: Windows::Foundation::DateTime
body: <p>I'm using the Windows::Foundation::DateTime structure at the moment, and the value it's giving me for the UTC time (its UniversalTime member) is not a UNIX timestamp, and I can't find ANY documention on how to read it.  So I did a few tests:</p>
  
  <pre><code>Let 
  A equal 129862800600000000 where A is UniversalTime's value at 23:00 on 11/7/2012 
  and let
  B equal 129862476000000000 where B is UniversalTime's value at 15:00 on 11/7/2012
  
  We can there for assume that 8 hours of time in whatever format UniversalTime takes can be interpreted as A-B.  We therefore have
  A-B = 3246000000 = 8 hours
  (A-B)/8 = 405750000 = 1 hour
  ((A-B)/8)/60 = 6762500 = 1 minute
  (((A-B)/8)/60)/60 = 112708.(3...) = 1 second
  </code></pre>
  
  <p>This turned out to be completely incorrect.  If you add 405750000 to a DateTime object's UniversalTime member, for example, it most certainly does not add an hour to it.  Instead, it seems to add only 40 seconds.</p>
  
  <p>Basically I just need to be able to determine the number of days that have passed since the unix epoch.  </p>
  
  <p>In any event, if anyone has any advice or help, that would be great.</p>
  
  <p>Edit:
  I've also thought about the possibility that they're using a bitmask to get/set everything.  But I'm not sure how to go about checking that, at the moment.  (It's 4 AM, and I need to sleep.  rofl)</p>
  
  <p>Edit 2:
  Example for what I'm currently trying to do:</p>
  
  <pre><code>if((post_date.UniversalTime/(60*60*24))&gt;num_seconds_since_unix_epoch_for_current_day){
      date_formatter=ref new DateTimeFormatter("{month.abbreviated} {day.integer(1)}, {year.full} at {hour.integer(1)}:{minute.integer(2)}:{second.integer(2)}");
  }else{
      date_formatter=ref new DateTimeFormatter("Today at {hour.integer(1)}:{minute.integer(2)}");
  }
  date_string = date_formatter-&gt;format(post_date);
  </code></pre>
