よくある思い込み

ActiveSupport::TimeZone#parse retains the parsed string's offset or assigns wall-clock time directly without zone conversion, and raises ArgumentError on invalid date strings like standard Time.parse.

コントラクト

• ActiveSupport::TimeZone#parse with an explicit UTC offset converts the instant into the receiver's time zone representation rather than retaining the string's offset or treating the wall-clock time as local.
• ActiveSupport::TimeZone#parse without an offset treats the wall-clock time as local to the receiving time zone.
• ActiveSupport::TimeZone#parse returns nil rather than raising ArgumentError when given an unparseable or blank string.
• ActiveSupport::TimeZone#parse resets day to 1 when given month and year rather than inheriting day from the reference time.
• ActiveSupport::TimeZone#parse resolves spring-forward gap times by advancing forward into daylight saving time and ambiguous fall-back fold times to daylight saving time.
