I currently have it set to by date modified, however it is not accurate. For example, when I download something, it will often be near the bottom of the list, rather than the first item in the downloads folder. However, I have a stack for the downloads folder, and it organizes them *correctly* (one item doesn't seem right, but that's it).
It seems to be doing this because some downloaded items have custom date modified and created dates from when I downloaded them. I downloaded an application demo today, August 1st 2009, but it says May 2008 for date modified and created.
So, how can I organize the items by purely 'Date Downloaded' ?
Thanks.

The way I use my computer is by sorting files and folders by Date Modified. This way I'm always accessing the most recent items.
But I've noticed that after a period of time, folders and some files stop updating their Date Modified, and it drives me insane. One of my most important folders still displays 'Nov 25, 2008, 938 PM' as the last Date Modified, but I access it nearly every day. I need to know how to fix these modified dates, even if I have to run a script every other day.
I have that Refresh Finder button and it doesn't help...
