[rrd-users] fetch & resolution

Hello,

I'm having problems keeping a correct threshold.  I'm following the rule
of keeping the start and end time in multipules of the resolution, however
I'm consistently getting these weird two hour blocks.
(time/resolution)*resolution=new_time

Sample commands & values
rrdtool fetch file.rrd AVERAGE --resolution 300 --start 986112000 --end
988441200

I've also tryed
"rrdtool fetch file.rrd AVERAGE --start 986112000 --end 988441200
--resolution 300"
with no luck either.

I get values like this:
986112000 2.4330272163e+00 1.0916156465e+00
986119200 1.6588349489e+00 8.7417903591e-01
986126400 2.0804281935e+00 8.3188749901e-01
986133600 2.1068973953e+00 8.5510743454e-01
[...]

roughly translated:
04/01/2001 00:00 2.43 1.09
04/01/2001 03:00 1.66 0.87
04/01/2001 05:00 2.08 0.83A
[...]

What I'd like to be getting is nice clean 5 minute values for a full
month.  But I can't seem to get there.

Thanks for you help!
