Hi Anders,
Here are some brief answers. Good luck with your research.

As I mentioned off-list to you just now, I'm not the best person to
comment here but I'd be keen to know if anyone has done a comparison.

VOSON doesn't do this. I don't think a crawler can collect this data,
but I could be wrong. I think the best you can do is infer date of
link creation by comparing across the panels you plan to create e.g.
if link from i to j that is present at time t wasn't present in time
t-1, then it was created between t and t-1.

I'm not sure about SocSciBot (but can imagine it would) but with
VOSON, the answer is yes. In VOSON there is a facility to export the
hyperlink network in pajek format and my understanding is that format
can be read into UCInet.
