Does anyone have some info on how the timeShift function works?

I've tried a few variations on this:

http://localhost:8080/render/?width=586&height=303&_salt=1272319873.504&timeShift(system.loadavg_15min,-3h)
http://localhost:8080/render/?width=586&height=303&_salt=1272320472.061&target=timeShift(system.loadavg_15min,-3h)&from=-1d

But I just get "no data". I've verified there is data for that time period.  Is anyone using this function right now and if so, what's the proper syntax?
