[Xymon] xymon rrd value different from reported value

Hi all,

I'm having a weird problem for which I can't seem to hunt down a cause/solution. I have a custom script that's using SPLITNCV to store data, but the data stored in the rrd files are different from those reported by the script. Below you'll notice that at 10:48:34 customer_info is reported at 1, but in the rrd file it's showing 10:50:00 and  8.8008800880e-04. Any ideas?
