--insecure doesn't have anything to do with you not passing start/end arguments, which are required for the API call:
http://api.openstack.org/api-ref-compute-v2-ext.html
The novaclient allows start/end to be optional because it will default start to be 4 weeks ago and end to be tomorrow (now + 1 day). So I'd say this is a usage error.
