Why offsets are not time zones

An offset such as UTC−5 is a number. A time zone is a place plus a set of rules about when that number changes. New York is UTC−5 in winter and UTC−4 in summer; Phoenix is UTC−7 all year even though it shares a "Mountain" label with Denver. Store instants in UTC, store user preferences as an IANA zone name such as America/New_York, and let the library do the arithmetic.
