     1  Enhancement: introduce ocis driver treetime accounting
     2  
     3  We added tree time accounting to the ocis storage driver which is modeled after [eos synctime accounting](http://eos-docs.web.cern.ch/eos-docs/configuration/namespace.html#enable-subtree-accounting).
     4  It can be enabled using the new `treetime_accounting` option, which defaults to `false`
     5  The `tmtime` is stored in an extended attribute `user.ocis.tmtime`. The treetime accounting is enabled for nodes which have the `user.ocis.propagation` extended attribute set to `"1"`. Currently, propagation is in sync.
