Which format is illustrated by the example 2023-09-01T13:05:53Z?

• A. It uses a T to separate date and time
• B. It uses a space to separate date and time
• C. It uses a dash to separate date and time
• D. It uses a colon to separate date and time

Answer: (D)

ISO 8601 date-time formatting uses a T to separate the date from the time. In the example, 2023-09-01 is the date portion (with hyphens), then a T, then 13:05:53 as the time portion (with colons), and Z to indicate UTC. The key thing being tested is recognizing that the T is the divider between date and time, not a colon, space, or dash. The colon sits inside the time part, not between date and time, and there’s no space in this string.
