1. 确定所在的时区和服务器的时区设置是否正确。
2. 在AWS DMS的任务设置中，设置源和目标的时区。
3. 在MySQL中，设置session的时区。

具体的代码示例如下：

设置源和目标的时区：

{
   "TargetMetadata": {
      "TargetSchema": "my_schema",
      "SupportLobs": true,
      "FullLobMode": false,
      "TargetEndpointArn": "arn:aws:dms:us-east-1:123456789012:endpoint:ABCD1234",
      "TargetEngineName": "mysql",
      "TargetEngineVersion": "5.7",
      "ServerName": "myserver.example.com",
      "Port": 3306,
      "Databases": [ "mydatabase" ],
      "S3Settings": {
         "ServiceAccessRoleArn": "arn:aws:iam::123456789012:role/myaws-dms-s3-role",
         "ExternalTableDefinition": "CREATE EXTERNAL TABLE IF NOT EXISTS \n\t\tmytabname(ID INT, NAME VARCHAR(30), AGE INT)\n\t\tROW FORMAT DELIMITED FIELDS TERMINATED BY ',' \n\t\tLOCATION 's3://myaws-bucket/dms/output/' "
      },
      "ExtraConnectionAttributes": "timeZone=GMT"
   },
   "TargetEndpointArn": "arn:aws:dms:us-east-1:105559012345:endpoint:FHSCZLOE3CDIDDHWWLEUV3532E",
   "ReplicationTaskIdentifier": "task01",
   "MigrationType": "full-load",
   "TableMappings": "...",
   "SourceEndpointArn": "arn:aws:dms:us-east-1:123456789012:endpoint:ABCD1233",
   "ReplicationInstanceArn": "arn:aws:dms:us-east-1:123456789012:rep:ABCD1234"
}

设置MySQL session时区：

SET SESSION time_zone = 'UTC';
