title: ROBOCOPY puts the date 1/1/1980 on some copied files
body: <p>I am having an intermittent issue with ROBOCOPY copying files with an incorrect date.</p>
  
  <p>I am using ROBOCOPY to copy backup files from a local folder to a remote fileshare as a part of having a remote backup solution. The script is scheduled through task manager to run daily. Here is pseudo code:</p>
  
  <pre><code>ROBOCOPY E:\LocalFolder \\RemoteServer\FileShare\Folder *.bak
  </code></pre>
  
  <p>Most of the files copy with the correct file date, hovever one or two files sometimes will have the date of 1/1/1980. This presents a major issue with managing the backups in the fileshare because the dates are crucial to its management.</p>
  
  <p>What might causes this? 
  What can be done to prevent this behavior?</p>
