[UR-WG] aggregated records - Wallduration Processors

[piro at to.infn.it]

Hi Bart,

I must admit that I'm not an expert, but most probably you could use the
proberty TimeDuration with description="JobTime" for your purpose.
TimeDuration should be an arbitrary time measure that can be used for very
different purposes (see the UR spec.)
Doing so, you still can use the WallDuration (for total and/or average)
and Processors (total, average, ...) in the more traditional sense.

Cheers,
Rosario.
