I need to find the way of getting all the tenants and instance between the particular time period.

nova list --all-tenants will give all the tenants, So I need to get all the tenants which is created or deleted between the particular time period.

Is there any option available for the same with keystone for the same.

Like wise I need to get the same results for the instances too.

Some one let me know the way for achieving the same.
