Database triggers are a marvelous thing.  Is this wrong?

(TimeCurrent-TimeLastTime)               = Inbound bits/sec

We chose this because it doesn't matter if it is 30 seconds or 8 minutes
between sample points, it is all normalized in that period.  I do
realize that it is an average within that window, but all we need to do
is tune the cron job (how often we poll) to increase resolution.
