No, points mash together size and uncertainty. A task that's "3-9 days" will have fewer points than a task that's "3-9 weeks". And a real that's "3 months give or take a week" will have more points than either.
Of course, there's actually no such thing as a "3 months give or take a week" estimate for a task. It's basically impossible in programming to have a task that takes that long with that low a level of uncertainty. So in reality, time estimates have the same properties as points: the higher a time estimate, the more uncertainty it represents.
