[netflow-tools] flow_start and flow_finish

I'm confused about the flow_start and flow_finish fields of
store_flow_complete.  The values that I'm getting don't seem to
correspond to unix timestamps (even after running them through ntohl).
The store_format_flow() function formats them as intervals, but that
doesn't make sense either.  Is this a bug in netflow parsing?
