Thank you for the interest in NodeXL!
Time is of the essence for the NodeXL Team!
Today, NodeXL can be forced to do basic time related operations by adding time data to the edges and vertices worksheet and using Dynamic Filters to reveal and hide specific time slices in the network. Few features explicitly make this easy right now.
You can group vertices by a time attribute and then get metrics calculated for each group/time slice.
We do not yet enable grouping of edges.
Some people (with great patience) have created impressive results with some effort. An example is the recent work from Brian Keegan at Northwestern University, mapping the changing network forming around Wikipedia pages associated with the Sendai earthquake,
tsunami, and nuclear crises.

Soon, we plan to improve time support in NodeXL. We will make Brian's work much easier by allowing users to specify a start and end time, a time window, and an increment. NodeXL will then automate slicing through each filter setting and perform
an operation after each slice, like generating an image file of the contents of the network visualization pane or calculating metrics on just what is visible in that time slice.
