Uptime Plugin problem with the inventory

Hello !

I am currently trying to install th plugin Uptime on my OCS server (working on Debian) , the issue I'm facing is that the inventory does not always inventory the information about Uptime.
When I force an inventory from the command line (Windows), like : OCSInventory.exe /force /xml  it works perfectly and I do get an XML file with the uptime information.
But when I launch the agent manually with the icon in the taskbar, I do not have the information I want in the generated XML file, there is nothing about uptime. And when the inventory is done automatically it's the same.

So, my uptime database is still empty but I know that the script is working and I can get the information but only if I force it manually.

Any thoughts ? ;)

OCS Server version : 2.3.1
OCS Agent version : 2.3.0

Thanks a lot !
