title: s3cmd put -preserve flag does not preserve file creation /Modified date when copied to s3 bucket
body: <p>I am copying files for AWS ec2 to AWS s3 bucket, with --preserver flag to preserver to file create and modified date, but once file is copied to s3bucket, "s3cmd ls s3://bucket-name/" command list the file upload time as file time, it does not preserve the original file creation date-time. I am using following command(s3cmd put --preserve xyz.log s3://bucket-name/) to copy the file.  Though s3cmd help list the --preserve or -p as something you can use to preserve the date it does not seems to be working.  </p>
  
  <p>Has anybody run in to this kind of issue and can point me what I am doing wrong.</p>
  
  <p>I also tried s3cmd sync but sync command also behave same way, though I would prefer to use put. </p>
  
  <p>s3cmd put --preserve xyz.log s3://bucket-name/</p>
  
  <p>Thanks,</p>
