this is the offset comes from https://github.com/apache/arrow-rs/blob/master/arrow/src/compute/kernels/cast_utils.rs#L205-L220 ```rust /// Interprets a naive_datetime (with no explicit timezone offset) /// using the local timezone and returns the timestamp in UTC (0 /// offset) fn naive_datetime_to_timestamp(naive_datetime: &NaiveDateTime) -> i64 { // Note: Use chrono APIs that are different than // naive_datetime_to_timestamp to compute the utc offset to // try and double check the logic let utc_offset_secs = match Local.offset_from_local_datetime(naive_datetime) { LocalResult::Single(local_offset) => { local_offset.fix().local_minus_utc() as i64 } _ => panic!("Unexpected failure converting to local datetime"), }; let utc_offset_nanos = utc_offset_secs * 1_000_000_000; naive_datetime.timestamp_nanos() - utc_offset_nanos } ``` -- This is an automated message from the Apache Git Service.
