Doc Text:
.Buckets no longer have incorrect time stamps Previously, buckets created by the Simple Storage Service (S3) API on the Ceph Object Gateway before mounting the Ganesha NFS interface had incorrect time stamps when viewed from NFS. With this update, the NFS service uses time stamps that are based on the correct times of creation or modification of buckets. As a result, buckets created by the S3 API no longer have incorrect time stamps.

Description shylesh 2016-07-23 19:21:58 UTC 
Description of problem:
Few buckets were created with objects from s3 apis on rgw. Later when we instantiate ganesha and mounted using nfs mount . Now observe the timestamp for these directories (rgw buckets) it will be too old.

for ex :

[root@magna110 mnt]# ll
total 0
drwxrwxrwx. 3 root       root       0 Jan  1  1970 another-missed-hellonew-another-newad-bucket-creation
drwxrwxrwx. 3 root       root       0 Jan  1  1970 hellonew-another-newad-bucket-creation
drwxrwxrwx. 3 root       root       0 Jan  1  1970 missed-hellonew-another-newad-bucket-creation
drwxrwxrwx. 3 4294967294 4294967294 0 Jul 23 13:11 nfsbucket


observe timestamp for first three directories its "Jan 1 1970" . but buckets created later has proper time stamp.


mount command used
====================
mount -t nfs -o nfsvers=4.1,sync,noauto,soft,proto=tcp magna116.ceph.redhat.com:/ /mntr

Comment 2 Matt Benjamin (redhat) 2016-07-25 15:34:00 UTC 
Agree, the timestamp for these buckets -should- be an RGW timestamp, not 0.  Not sure if this can be changed before 2.1.
