DLM/GetLifecyclePolicy fails to parse timestamps

[SimonMachine]

Describe the bug

When trying to get a snapshot lifecycle policy using the ''dlmClient' and 'getLifecyclePolicy' method, get an unexpected exception regarding date parse.

Expected Behavior

dlmClient can parse the timestamp and get the policy object.

Current Behavior

error log: Unable to unmarshall response (Text '1.655421227201E9' could not be parsed at index 0). Response Code: 200, Response Text: OK

('1655421227.201E9' is the time when I created the dlm policy. )

Reproduction Steps

Create a Snapshot lifecycle policy from the aws console. Use the aws java sdk to fetch it using the getLifecyclePolicy method.

AwsBasicCredentials awsCredentials = AwsBasicCredentials.create(accessKey, secretKey);
DlmClientBuilder dlmClientBuilder = DlmClient.builder()
        .credentialsProvider(StaticCredentialsProvider.create(awsCredentials))
        .region(Region.of(region));
DlmClient client = dlmClientBuilder.build();
GetLifecyclePolicyRequest getLifecyclePolicyRequest=GetLifecyclePolicyRequest.builder().policyId(policyId).build();
GetLifecyclePolicyResponse lifecyclePolicy = client.getLifecyclePolicy(getLifecyclePolicyRequest);

Hi @SimonMachine thank you for the callout, I can reproduce the error.

According to the service model, the timestamp should be iso8601:

https://github.com/aws/aws-sdk-java-v2/blob/4c1e3f6a5369648fc4045221c679484022b62e3e/services/dlm/src/main/resources/codegen-resources/service-2.json#L1183-L1186

and the service is sending 1.655421227201E9 in the response.

And the "timestampFormat":"iso8601" trait was added to the model in Feb 2019, probably to fix the previous issue - https://github.com/aws/aws-sdk-java-v2/issues/1053.

I'll reach out to the DLM service team.

The DLM is investigating the root cause.

Since this is an issue on the service side, it may impact other SDKs, so I'm transferring this to the aws-sdk repo for visibility.

I'll update here with any new info.
