How many websites is this actually an issue for? I know web developers get all impressed with themselves about putting fancy images on their web pages, but the vast majority of them are simply useless decoration.

So have a built-in widget in the browser that takes a time in UTC from the server and converts it to local time (if the user has that setting enabled in their browser settings) based on the computer's time zone.
Even client side Javascript could do this without having to tell the server anything about the client's time zone.

How about just letting the user select the right download button?
