Hi -- I use TimeSlice. It used to be from Casady and Greene, but I think it got sold, or something. I'm on version 2.5.1.
It was somewhat pricey (not shareware) -- in the $60 range, I believe. But it does what I need it to do. It has export features which, quite frankly, I've never even used.
I believe there's a demo out there of it.
Also, I know I downloaded once a demo for something called Time Cache (in fact, I just trashed it yesterday!) That one seemed promising, too.
Try Tucows -- the software site -- and do a search, as well. There probably are cheaper shareware programs out there.
