I don't really think it has all that much more time. There are really two things we're talking about here. First, how much angular deflection you get for a given wind and second, how much that angular deflection moves the bullet. Of course if the deflection is farther down range then it causes less wind drift on the target.
I've never been good at remembering numbers so I ran a few of test cases with a point mass program. They are all 10 mile/hour winds. One is a constant wind from 0 to 1000 yards. The next is from 0 to 100 yards and the third is 500 to 600 yards. All have trajectories to 1000 yards.
Here are the URLs:
Please note the version number of the program running these (<1) so I'm covering my butt.
