Question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "However, even if UTC is used internally, the systems still require information on time zones to correctly calculate local time where it is needed. Many systems in use today base their date/time calculations from data derived from the IANA time zone database also known as zoneinfo."?
Answer:
What information is needed?
