Thanks Benjamin. That was the missing piece to the puzzle. I didn't realize by choosing a 1day step time RRD would write intervals at 16:00 PST(00:00 GMT) instead of creating intervals beginning with my --start time argument.

It seems no matter what time I choose for --start on a create, the dump file shows my datapoints are all 16:00:00 PST. I can hardcode the epoch time or I can let it default to now-10s, I still get 16:00:00 PST. Here's the snippet I'm using: my $midnight = timelocal( 0, 0, 0, (localtime)[3,4,5] ); my $one_year = 60*60*24*365; RRDs::create( $FILE, '--start', ( $midnight - $one_year - 86400 ), '--step', '86400', 'DS:hits_by_date:GAUGE:172800:0:99999999', 'RRA:AVERAGE:0.5:1:360', 'RRA:AVERAGE:0.5:30:12', 'RRA:AVERAGE:0.5:360:10' ); And here's a snippit from the dump: <database> <!-- 1999-12-05 16:00:00 PST / 944438400 --> <row><v> NaN </v></row> <!-- 1999-12-06 16:00:00 PST / 944524800 --> <row><v> NaN </v></row> <!-- 1999-12-07 16:00:00 PST / 944611200 --> <row><v> NaN </v></row> <!-- 1999-12-08 16:00:00 PST / 944697600 --> <row><v> NaN </v></row> Anyone have any suggestions? All comments would be greatly appreciated.
