Deprecated utcnow() method used in the test patch

[SmartManoj]

Describe the bug

Instance ID: django__django-11848
Category: Verified

The test patch currently uses the deprecated utcnow() method from the datetime module to retrieve the current UTC. As of Python 3.12, utcnow() has been deprecated and is scheduled for removal in future versions of Python.

Question: Should the agent be producing deprecated code? If not, replacing utcnow with now will solve this.

Steps/Code to Reproduce

swebench.cloud eval result

Expected Results

Test patch should use now()

Actual Results

Test patch have utcnow()
