Create an Automated Time Greeter application in Python using system time libraries to process automated tracking logs.
Requirements
1. Inside the application, import the built-in datetime module to capture dynamic hourly timestamp values directly within a structural loop.
2. The application will process discrete simulation target configurations inside a test list instead of using blocked dynamic prompts.
3. Run a continuous loop structure to iterate over each time interval metric sequentially until the array boundaries are exhausted.
4. Validation Logic :

1. Trap invalid boundary integers using conditional testing blocks to filter numbers outside typical 24-hour properties.
2. Enforce explicit hour range matching comparisons to isolate specific morning, afternoon, or evening conditions safely.
3. Monitor runtime parsing flows to generate fallback default state strings if out-of-range numerical sequences pass.

5. Print a clear validation greeting message displaying the current simulated hour index and corresponding string response on screen.
