copied and pasted from earlier (I don't have any archive links).  They're 
not related to the iterator, they have to do with some types in date-time 
about which I should need to know nothing.

maybe, I get no errors compiling my program now, but I have some new warnings:
the two size_t to int ones are pesky, the others, I can't tell if there 
actually IS any possibility of losing data.
