Adding data in the past

Hi,

I am stuck with aan annoying issue with rrdtool.

I want to add data in the past but cannot figure how to do so.

So far, I have only added data now, but I want to reconstruct an history
from data gathered from an older log file.

I am trying:

$ rrdtool update PUA.Win32.Packer.Upx-48.rrd 1425432131:1 
ERROR: PUA.Win32.Packer.Upx-48.rrd: illegal attempt to update using time 1425432131 when last update time is 1457517650 (minimum one second step)

Which obviously is not working, but I cannot see where is my error.

1425432131 is the tmiestamp for Wed Mar  4 08:22:11 2015

Thanks in advance,

Olivier
