What's the point of this UN resolution?

Iran reacted to the news of this resolution exactly like everyone should have expected. They're a proud nation and don't like being bullied. So what purpose does this resolution provide? They couldn't wait for the Iranian response to the Western incentive proposal on 22 August?

Iran’s government will reject a proposed United Nations resolution that would give it until August 31 to suspend uranium enrichment or face the threat of international sanctions, state-run radio says.

“Iranians will not accept unfair decisions, even in the framework of resolutions by the international bodies,” the radio commentary said.

There has been no official comment to the draft resolution, but state radio often is thought to provide the Iranian government line.

The resolution was formally circulated to the full 15-member UN Security Council on Friday and will probably be adopted next week.

“Ultimatum and deadline cannot be acceptable to us,” the commentary said, accusing the US and its allies of making what it called an illegal demand by the United States, France, Germany and Britain.
