  FYI:  datetime.datetime.fromtimestamp(mod_time)
  Is probably what I was looking for. However, for my
  purposes - I'm going to take another approach.
  Every uploaded file is defined in an object stored on my
  workstationr:
  I will store the MDTM string after upload and then on the next
  upload, compare the stored string with the return value
  from ftp.sendcmd('MDTM ' + filename)
  Thanks for the input.
