흔히 이렇게 알고 있다

In European timezones such as Europe/Dublin, winter periods are standard time with dst? returning false and summer periods are daylight saving time with dst? returning true.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• In Europe/Dublin under tzdata 2026c, winter periods have dst? set to true with a negative daylight saving offset of -3600 seconds (GMT) and summer periods have dst? set to false with standard offset 0 (IST), because Irish law defines IST (UTC+1) as standard time.
• Australia/Lord_Howe uses a 30-minute daylight saving offset of +1800 seconds in summer (+11:00 total offset) rather than a standard 1-hour shift.
• Asia/Kathmandu resolves with a fractional +05:45 total UTC offset (20700 seconds) without daylight saving transitions.
• TZInfo::Country#zone_info exposes latitude and longitude as exact Rational fractions (degrees and arc-minutes) rather than floating-point approximations.
• Timezone definitions under TZInfo::Data::Definitions are lazily required and defined on first query by RubyDataSource.
