title: How preserve and keep timestamp of original modified date for file when uploading to Amazon S3?
body: <p>Is there any way either in Java or using s3cmd to keep and preserve the modified date on the file as opposed to the LastModified Amazon sets with sysdate when you actually upload the file to S3 ?</p>
  
  <p>Amazon S3 seems to use the upload timestamp as the LastModified on the file, and not the original file date/timestamp. </p>
  
  <p>Thanks. </p>
