No, you do not.  At least not in your example (I'm sure some
rounding will occur, eventually, somewhere).

You should RTFM http://oss.oetiker.ch/rrdtool/doc/rrdcreate.en.html
section on counter types.

Also see my site for some more information.

Delta_value is 54000000000 (because you say so!), delta_time is 900
(because of timestamps 1177498800 and 1177497900), thus the computed
rate is 54000000000/900 = 60000000 = 6.0e+07
