[rrd-users] Start time with rrdtool create

[Glenn MacGregor]

Hi All,
 
I am using rrdtool 1.2.23 trying to create a rrd file starting 1 month
ago. 
 
rrdtool create test.rrd --step 300 --start 1180670400
DS:param:GAUGE:600:U:U RRA:AVERAGE:0.5:1:1200 RRA:AVERAGE:0.5:6:336
RRA:AVERAGE:0.5:24:372 RRA:AVERAGE:0.5:144:730
 
output from rrdtool xport:
<start>1183646700</start>
<step>300</step>
<end>1183733100</end>
 
As you can see the start time is quite a bit different than the start
time I input. Is there a reason for this discrepancy?
 
Thanks
 
 Glenn
