They are the same in that they are both poorly named and incompletely
implemented. :( Jeff Jensen and I tried to think it through and do it
right, but we simply couldn't predict all the features we'd want, nor
could we come up with a syntax that put rolled them all together. When
the revolution comes and we rewrite the grapher, these tags will be
the first into the guillotine! Let them eat cake! Or something...
So, here's a consise explanation of the difference:
"targets" lets you put multiple targets together on one page -- sorta
like opening up several browsers and navigating to several targets,
but all on one HTML page.
"mtargets" lets you take the data from several targets and assemble a
new graph out of that data -- either in aggregate (i.e. the sum of all
WAN links) or overlayed.

To do this, you'd make a new target, for example "both":
target both
mtarget = "target-1; target-2"

You are trying to put a string into an RRD, which is not possible. You
could use an EXEC script to fetch the value then do pre-processing on
it -- in this case the pre-processing would be to turn the formatted
time string into a number of seconds.
