title: Binary to Date (C#) 64 Bit Format
body: <p>We have a binary file from which we have identified the following dates (as Int64). We now the following facts about the Date/Time format;</p>
  
  <ul>
  <li>The 64 bit Date has a resolution to the microsecond</li>
  <li>The 64 bit Date has a range of 4095 years</li>
  <li>The Int64 9053167636875050944 (0x7DA34FFFFFFFFFC0) = 9th March 2010</li>
  <li>The Int64 9053176432968073152 (0x7DA357FFFFFFFFC0) = 10th March 2010</li>
  <li>The Int64 9053185229061095360 (0x7DA35FFFFFFFFFC0) = 11th March 2010</li>
  <li>The Int64 9053194025154117568 (0x7DA367FFFFFFFFC0) = 12th March 2010</li>
  </ul>
  
  <p>Any help on figuring out a way to convert this to a valid C# Date/Time is appreciated.</p>
