Ceph » rgw

Hi team,

Ceph doesn't return the correct timestamp in getObject call

LastModified field in metadata of the ListObject() call contains milliseconds values. On the other hand lastModidied field in metadata of GetObject() call is always with milliseconds as all 0s.

Example 1

ListObject response

```

<ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/&quot;&gt;&lt;Name&gt;s3listobjectstests.testv2simple-20200917t215132-zpej2auwa83hope&lt;/Name&gt;&lt;Prefix&gt;&lt;/Prefix&gt;&lt;MaxKeys&gt;1000&lt;/MaxKeys&gt;&lt;IsTruncated&gt;false&lt;/IsTruncated&gt;&lt;Contents&gt;&lt;Key&gt;a&lt;/Key&gt;&lt;LastModified&gt;2020-09-17T21:51:38.067Z&lt;/LastModified&gt;&lt;ETag&gt;&quot;8d777f385d3dfec8815d20f7496026dc&quot;&lt;/ETag&gt;&lt;Size&gt;4&lt;/Size&gt;&lt;StorageClass&gt;STANDARD&lt;/StorageClass&gt;&lt;Type&gt;Normal&lt;/Type&gt;&lt;/Contents&gt;&lt;Contents&gt;&lt;Key&gt;b&lt;/Key&gt;&lt;LastModified&gt;2020-09-17T21:51:38.253Z&lt;/LastModified&gt;&lt;ETag&gt;&quot;8d777f385d3dfec8815d20f7496026dc&quot;&lt;/ETag&gt;&lt;Size&gt;4&lt;/Size&gt;&lt;StorageClass&gt;STANDARD&lt;/StorageClass&gt;&lt;Type&gt;Normal&lt;/Type&gt;&lt;/Contents&gt;&lt;Contents&gt;&lt;Key&gt;c&lt;/Key&gt;&lt;LastModified&gt;2020-09-17T21:51:38.304Z&lt;/LastModified&gt;&lt;ETag&gt;&quot;8d777f385d3dfec8815d20f7496026dc&quot;&lt;/ETag&gt;&lt;Size&gt;4&lt;/Size&gt;&lt;StorageClass&gt;STANDARD&lt;/StorageClass&gt;&lt;Type&gt;Normal&lt;/Type&gt;&lt;/Contents&gt;&lt;KeyCount&gt;3&lt;/KeyCount&gt;&lt;/ListBucketResult>

List Object timestamp is 1600380214350
