 As discussed on the call, I think there are broader problems with
 transferring timestamps than just the structure size.  So I'm hoping
 we can work out how to not transfer them at all and avoid this change. 
This change is not related to the fact that we ignore or use them. It's
about making the flow entries the same size, which we need, at least
with this implementation.
