----------------------------------------
The exact stack message :
{code}

> Openstack Nova listing details fails when using changes-since

> Key: JCLOUDS-910
> URL: https://issues.apache.org/jira/browse/JCLOUDS-910
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-labs-openstack
> Affects Versions: 1.8.1, 1.9.0
> Environment: Vanilla Openstack Cloud
> Reporter: Pierre Souchay
>
> When using code to limit the results from Nova, the argument changes since is
> sent as a long as a query parameter.
> This attribute is not and was never supported by Nova with such format, date
> must be an ISO date as seen here:
> https://github.com/openstack/nova/blob/master/nova/api/openstack/compute/servers.py#L163
>
> Problem can be reproduced that way :
> {code}
> nova.getNovaApi()
> .getServerApiForZone(defaultZone)
> .listInDetail(PaginationOptions.Builder.changesSince(new
> Date()))
> .iterator()
> {code}
> This code fails with HTTP 400 since format for changes-since is incorrect (at
> least with Openstack Icehouse and Later)
> The problem may probably be fixed here :
> apis/openstack-nova/src/main/java/org/jclouds/openstack/nova/v2_0/options/ListOptions.java
> at line 64 where
> {code}
> this.queryParameters.put("changes-since", checkNotNull(changesSince,
> "changesSince").getTime() / 1000 + "");
> {code} is simply using long conversion instead of sending ISO format date
