UWS 1.1 job list, sorting NULL values

Hi Paul and Grégory,

Yes, that's exactly what we do: wait for the PHASE=RUN command before
validation.

> If you set the startTime on the jobs
that enter the ERROR phase as a result of this validation then the end
result for the client would be indistinguishable from the approach that
Grégory uses in his library. It is always worth remembering that UWS is
just a facade and that there is a fair degree of freedom in the
underlying implementation as long as the interface behaves in a way that
the client expects.

Agreed, I will do that, it sounds very reasonable. I think this is not
so clear from the definition of startTime as the time when the job
starts execution, but it will make sense to the user.

I am glad we had these discussions, since it makes it all much clearer
to me. Thanks a lot!

Cheers,

Kristin
