Charlie's method prevents the use of an index on the timestamp column. Probably not a big deal, because there probably isn't one, but it's something to consider. I'd imagine that it's also slower in general, because EVERY record has to have a date operation performed as well as a comparison, while using CF to create a range (as you and I proposed) only requires a couple date operations regardless of the number of records.
