title: Is there an OpenXml (C#) date/time format for "m/d/yyyy h:mm tt" [AM/PM]?
body: <p>Looking at the list <a href="http://closedxml.codeplex.com/wikipage?title=NumberFormatId%20Lookup%20Table" rel="nofollow noreferrer">here</a>, you can see:</p>
  
  <ul>
  <li>0     - General</li>
  <li>1     - 0</li>
  <li>2     - 0.00</li>
  <li>3     - #,##0</li>
  <li>4     - #,##0.00</li>
  <li>9     - 0%</li>
  <li>10    - 0.00%</li>
  <li>11    - 0.00E+00</li>
  <li>12    - # ?/?</li>
  <li>13    - # ??/??</li>
  <li>14    - d/m/yyyy</li>
  <li>15    - d-mmm-yy</li>
  <li>16    - d-mmm</li>
  <li>17    - mmm-yy</li>
  <li>18    - h:mm tt</li>
  <li>19    - h:mm:ss tt</li>
  <li>20    - H:mm</li>
  <li>21    - H:mm:ss</li>
  <li>22    - m/d/yyyy H:mm</li>
  <li>37    - #,##0 ;(#,##0)</li>
  <li>38    - #,##0 ;Red</li>
  <li>39    - #,##0.00;(#,##0.00)</li>
  <li>40    - #,##0.00;Red</li>
  <li>45    - mm:ss</li>
  <li>46    - [h]:mm:ss</li>
  <li>47    - mmss.0</li>
  <li>48    - ##0.0E+0</li>
  <li>49    - @</li>
  </ul>
  
  <p>You can see <em>most</em> cases seem to be covered, 22 gets very close, but what I really need is <strong>m/d/yyyy h:mm tt</strong> - does anyone know of a way to set that in OpenXml?  Thank you.</p>
