### 🚑 其他信息

The issue asks how to make ProFormDateTimePicker a controlled component, but provides no file, test, example code, or expected behavior. First clarify the intended value and change handling with a minimal reproduction, then locate the component entry point and add or update a test that demonstrates the controlled behavior.
