To Reproduce Steps to reproduce the behavior:

1. Deploy OCP4.18
2. Set any timezone except UTC+0:00, for example, Asia/Tokyo UTC+9:00, according to https://access.redhat.com/solutions/5487331
3. Deploy RHOSO18 control plane
4. Check date command results between cinder, manila and nova.

Expected behavior

• All openstack related service should use UTC timezone.

Bug impact

• By this behavior, cinder and manila services have different timezone according to the OCP configuration.
  Due to that, it increased the difficulty of troubleshooting and log analysis.

Known workaround

• Configure OCP nodes with UTC
