System Uptime Info Label?

i thought i saw a changelog entry talking about adding the system uptime to the system info screen (on 8/20/2005?).

i'm wondering if i can just that data in an info label on one of the windows?

could it be as simple as "system.uptime"?

ok, i'm looking at the code for guiwindowsysteminfo.cpp at this link:

http://cvs.sourceforge.net/viewcvs....=markup

i see a function called "getsystemuptime" in this code...is there someway i can call this up in python or reference it as and <info> tag in an xml file?
