novemberkilo opened a new issue #901: URL: https://github.com/apache/arrow-rs/issues/901
``` #[cfg(feature = "chrono-tz")] #[test] fn test_temporal_array_timestamp_hour_with_dst_timezone_using_chrono_tz() { // // 1635577147 converts to 2021-10-30 17:59:07 in time zone Australia/Sydney (AEDT) // The offset (difference to UTC) is +11:00. Note that daylight savings is in effect on 2021-10-30. // When daylight savings is not in effect, Australia/Sydney has an offset difference of +10:00. let a = TimestampMillisecondArray::from_opt_vec( vec![Some(1635577147000)], Some("Australia/Sydney".to_string()), ); let b = hour(&a).unwrap(); assert_eq!(17, b.value(0)); } ``` This test [fails](https://github.com/novemberkilo/arrow-rs/commit/473e2e4eb4f3b47aa7110d1a23444647b1109665) - it returns 16 instead of 17 and demonstrates that the offset for the timezone is not correctly taking daylight savings into account. __Originally posted by @novemberkilo in https://github.com/apache/arrow-rs/pull/849#issuecomment-955647565__ -- This is an automated message from the Apache Git Service.
