### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version master ### What's Wrong? The value of timestamp type data obtained through arrow is incorrect. <img width="980" alt="image" src="https://github.com/user-attachments/assets/557ceca9-b6ad-44b5-a56c-253e33f52d2c";> <img width="1123" alt="image" src="https://github.com/user-attachments/assets/ae00da53-fc5b-4499-a617-93330de3c90f";> ### What You Expected? The actual value is 2024, but the extracted value is 1970. ### How to Reproduce? - ddl ``` -- e2e_sink.doris_e2e_unique_table definition CREATE TABLE `doris_e2e_unique_table` ( `F_ID` bigint(20) NULL, `F_INT` int(11) NULL, `F_BIGINT` bigint(20) NULL, `F_TINYINT` tinyint(4) NULL, `F_SMALLINT` smallint(6) NULL, `F_DECIMAL` DECIMAL(18, 6) NULL, `F_LARGEINT` largeint(40) NULL, `F_BOOLEAN` boolean NULL, `F_DOUBLE` double NULL, `F_FLOAT` float NULL, `F_CHAR` char(1) NULL, `F_VARCHAR_11` varchar(11) NULL, `F_STRING` text NULL, `F_DATETIME_P` datetime(6) NULL, `F_DATETIME` datetime NULL, `F_DATE` date NULL, `MAP_VARCHAR_BOOLEAN` MAP<text,boolean> NULL, `MAP_CHAR_TINYINT` MAP<text,tinyint(4)> NULL, `MAP_STRING_SMALLINT` MAP<text,smallint(6)> NULL, `MAP_INT_INT` MAP<int(11),int(11)> NULL, `MAP_TINYINT_BIGINT` MAP<tinyint(4),bigint(20)> NULL, `MAP_SMALLINT_LARGEINT` MAP<smallint(6),decimalv3(20, 0)> NULL, `MAP_BIGINT_FLOAT` MAP<bigint(20),float> NULL, `MAP_LARGEINT_DOUBLE` MAP<decimalv3(20, 0),double> NULL, `MAP_STRING_DECIMAL` MAP<text,decimalv3(10, 2)> NULL, `MAP_DECIMAL_DATE` MAP<decimalv3(10, 2),datev2> NULL, `MAP_DATE_DATETIME` MAP<datev2,datetimev2(6)> NULL, `MAP_DATETIME_CHAR` MAP<datetimev2(6),text> NULL, `MAP_CHAR_VARCHAR` MAP<text,text> NULL, `MAP_VARCHAR_STRING` MAP<text,text> NULL ) ENGINE=OLAP UNIQUE KEY(`F_ID`) COMMENT 'OLAP' DISTRIBUTED BY HASH(`F_ID`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "is_being_synced" = "false", "storage_format" = "V2", "light_schema_change" = "true", "disable_auto_compaction" = "false", "enable_single_replica_compaction" = "false" ); ``` -data ``` INSERT INTO `doris_e2e_unique_table` (F_ID, F_INT, F_BIGINT, F_TINYINT, F_SMALLINT, F_DECIMAL, F_LARGEINT, F_BOOLEAN, F_DOUBLE, F_FLOAT, F_CHAR, F_VARCHAR_11, F_STRING, F_DATETIME_P, F_DATETIME, F_DATE, MAP_VARCHAR_BOOLEAN, MAP_CHAR_TINYINT, MAP_STRING_SMALLINT, MAP_INT_INT, MAP_TINYINT_BIGINT, MAP_SMALLINT_LARGEINT, MAP_BIGINT_FLOAT, MAP_LARGEINT_DOUBLE, MAP_STRING_DECIMAL, MAP_DECIMAL_DATE, MAP_DATE_DATETIME, MAP_DATETIME_CHAR, MAP_CHAR_VARCHAR, MAP_VARCHAR_STRING) VALUES (1, 10, 10000000000, 1, 100, 123.456789, 9223372036854775807, TRUE, 3.14159, 2.71828, 'A', 'Hello World', 'Sample text for the string field.', '2024-07-19 12:00:00.123456', '2024-07-19 12:00:00', '2024-07-19', {'key1': TRUE, 'key2': FALSE}, {'A': 1, 'B': 2}, {'text1': 1, 'text2': 2}, {1: 1, 2: 4}, {1: 10000000000}, {100: 9223372036854775807}, {10000000000: 3.14}, {9223372036854775807: 3.14}, {'value1': 123.45, 'value2': 678.90}, {123.45: '2024-07-19'}, {'2024-07-19': '2024-07-19 12:00:00'}, {'2024-07-19 12:00:00': 'Datetime example'}, {'key1': 'value1', 'key2': 'value2'}, {'keyA': 'Sample text', 'keyB': 'Another text'} ) ``` -code ``` // Licensed to the Apache Software Foundation (ASF) under one // or more contributor license agreements.
