Backport #17908
Updated by Nathan Cutler over 7 years ago
https://github.com/ceph/ceph/pull/11990 when we get the stat of a bucket with swift stat bucket api, the response element "X-Timestamp" is zero, i.e. ``` [root@c7 weiqm]# swift stat my-bucket-3 Account: v1 Container: my-bucket-3 Objects: 0 Bytes: 0 Read ACL: Write ACL: Sync To: Sync Key: Accept-Ranges: bytes X-Storage-Policy: default-placement X-Container-Bytes-Used-Actual: 0 X-Timestamp: 0.00000 X-Trans-Id: tx00000000000000000000f-00577a3762-31d43-default Content-Type: text/plain; charset=utf-8 ```
