Which statement describes how dates and times are formatted?

• A. They are free-form and may include any separator
• B. They use a non-ISO standard
• C. They use the ISO 8601 standard with a T separator
• D. They require the time zone to be omitted

Answer: (C)

Dates and times are standardized using ISO 8601, which formats as YYYY-MM-DDTHH:mm:ss with a T between the date and the time. This T boundary removes ambiguity about where the date ends and the time begins and supports consistent interpretation across different locales. While time zones are often included (as Z or an offset), omitting them isn’t required and can create confusion in global contexts. Free-form formats or non-ISO standards can vary widely in separators and order, leading to misinterpretation. So describing the formatting as ISO 8601 with a T separator best captures how dates and times are intended to be written.
