흔히 이렇게 알고 있다

Passing positive offset strings like tzstr('EST+5') or configuring posix_offset=True produces a timezone 5 hours ahead of UTC.

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

컨트랙트

• tzstr('EST+5') produces an offset of -5 hours (UTC-5) per POSIX standard inversion, whereas tzstr('UTC+5') defaults to +5 hours (UTC+5) unless posix_offset=True is set
• tzstr('UTC+5') with default posix_offset=False produces +5 hours (UTC+5) while tzstr('UTC-5') produces -5 hours (UTC-5)
• tzstr('UTC+5', posix_offset=True) produces -5 hours (UTC-5) under strict POSIX compliance
• gettz() with TZ environment variable set to a POSIX string inherits tzstr parsing semantics
• tzstr with POSIX transition rules correctly switches between standard and daylight saving time offsets
