Re: variables for yesterday and today

Yes, that's much better.  But it occurs to me also that this always 
resolves to 65536.  So why not just use the constant and save processing 
time?  The answer is that this would cause an overflow.  

But then the expression "(% 86400 (lsh 1 16))" also always yeilds one 
and the same integer expression, 20864, and "(/ 86400 (lsh 1 16))" 
always yeilds 1.  Is there any reason not to replace these expression 
with the constants they're always going to resolve to?


Thanks everyone for their assistance.
