When listing dates and times, what approach avoids confusion about time zones?

• A. List each date with its local time and corresponding time zone.
• B. Convert all times to the recipient's time zone only and omit others.
• C. Include all times in a single line without zones.
• D. Use the 24-hour clock without timezone labels.

Answer: (D)

To avoid confusion about time zones, attach a time zone to every listed time. When you show the date and time with its time zone, anyone reading it knows exactly when it is meant, no matter where they are. This prevents misinterpretation that can happen if times are given in local formats or in a single line without zones. Merely using a 24-hour clock isn’t enough if the time zone isn’t stated, because 14:00 in one location can refer to a different moment in another. A robust approach is to include the time zone (or use a universal reference like UTC with an explicit label, e.g., 14:00 UTC).
