Comment (by irl):

 If a bandwidth scanner's measurement threads crash but it's still writing
 out a bandwidth file, we'd be getting a load of files all with the same
 timestamp for a while. If we use the file_created timestamp then this
 won't happen. We still ''fall back'' to the timestamp field if there is no
 file_created field so we can still archive the older files.

 I don't want to be in a situation where a bandwidth scanner has been
 broken for a few days and we're putting those files into last month's
 tarball if we can avoid it.
