Ah, I see what you mean - he's looking for the last saved values, rather than the \
last update time. RRDs::lastupdate and RRDs::last are sort of named backwards, it \
seems to me.
In this case, I would either use RRDs::info (as Tobi suggested) or you could do it \
with a RRDs::fetch and a bit of work.

It's a little different than what Sean was looking for.
last() returns just a timestamp.
lastupdate() returns a timestamp with all corresponding values.
