Hi,
I have a problem with timestamps of objects created in Rados Gateway.
Timestamps are supposed to be in UTC timezone but instead I have strange
offset shift.
Server with Rados Gateway use MSK timezone (GMT +3). NTP is set, up and
running correctly. Rados Gateway and Ceph has no objects (usage log is
empty). Then I use Boto to create some buckets and objects:
$ date
Чтв Фев 26 11:29:05 MSK 2015
$ python fill_smth.py
$ date
Чтв Фев 26 11:29:16 MSK 2015
As you can see, my local time is *11*:29:05, in UTC it is *09*:29:05.
After that I fetch Rados Gateway usage log:
$ date
Чтв Фев 26 11:35:35 MSK 2015
$ radosgw-admin usage show --uid=2733d594-2f5a-46f7-9174-68000ce754c8

Timestamp is "2015-02-26 *05*:00:00.000000Z" so it means that it is
GMT -3 (expected timestamp is 2015-02-26 *09*:00:00.000000Z) . So it
means, that tiimezone offset applied 2 times.
Right now if I want to fetch any usage information on the time range I
have to query 3 hours back from UTC. The same problem with REST API.
Could you please advise or suggest me anything?
Thanks!
