Not really.  It's so that if the timestamp 'record' gets separated from
the hash you can still figure out what it's timestamp was.

$rate_ref = {
  'timestamp' => '12039911',
  'in'        => '2342341',
  'out'       => '53512',
};

$rates_ref->{$interface}->{$rate_ref->{'timestamp'}} = $rate_ref;

Only reason that comes to mind is that there is no data for that
timestamp in the original RRD file.  Without looking at the RRD data for
that period I couldn't tell you.
