can someone please advise  here-

I am using the S3 service on the latest localstack version,and using the Amazon's S3 Java SDK to perform all the operations with Java 8 (Additional configuration info : aws-sdk-java/1.11.542 Windows_10/10.0 Java_HotSpot(TM)_64-Bit_Server_VM/25.60-b23 java/1.8.0_60 scala/2.10.5 groovy/2.4.10 vendor/Oracle_Corporation)

Although creating a new bucket seems to working as expected, retrieving the buckets via list buckets operation throws the following exception through the SDK:
```
 java.lang.IllegalArgumentException: Invalid format: "2019-12-23 05:12:26.039447" is malformed at " 05:12:26.039447"). Response Code: 200, Response Text: OK

response-

<ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01"><Owner><ID>bcaf1ffd86f41161ca5fb16fd081034f</ID><DisplayName>webfile</DisplayName></Owner><Buckets><Bucket><Name>tst-adapter-us-west-2</Name><CreationDate>2019-12-23 02:17:43.014814</CreationDate></Bucket></Buckets></ListAllMyBucketsResult>
