You are solving a spreadsheet benchmark task in a real workbook. Objective: Produce the correct final workbook state for the expected answer region. What matters: - Only the values in the expected answer region will be graded. - The workbook is the answer. Instructions: 1. Read the workbook and inspect the relevant data region first. 2. Infer the required result for the provided workbook instance. 3. Write the final value(s) directly into the expected answer region. 4. Do not rely on prose, formulas in your chat response, pseudocode, or VBA as the answer unless the benchmark explicitly requires those to be written into cells. 5. If the natural-language task asks for a general method, formula, or macro, convert that into the concrete result needed for this workbook instance. 6. Keep your final text response short and only summarize the workbook cells you changed. Relevant data region(s): Expected answer region(s): C2:C100 Expected answer sheet(s): Task: How can I correct an error that occurs when calculating a 'Cut Off' time that should be half an hour before the 'STD' time, particularly when this calculation crosses over midnight? Additionally, how can I ensure that if there's no data present in columns A and B, then column C will display a blank cell instead of an error? Current formula is B2-TIME(0,30,0). Use the corrected formula in cell C2 of 'Sheet1' and apply it down the column to generate the final 'CUT OFF' times.
