Roger, will do.
There actually still is a small risk in the sequence: if the BEGIN
block starts *exactly* at midnight, to within the resolution of
gettimeofday(), then 'now' and 'today' will yield the same value so
the expected row counts will not be matched. This seems like an
acceptably small probability to me.
