ec2-provider -> FileNotfound with swift3-middleware

[Tino Schmeier]

Hello.

The expires-variable is set to 10 years in the future. This leads to the FileNotfound-Error (RequestTimeTooSkewed) because the swift3-middleware sets the timedelta-value to 10 minutes.

2013-03-12 11:21:37,135: juju.agents.machine@ERROR: Error starting unit: wordpress/2

juju-code juju/providers/ec2/files.py:
...
# URLs are good for 10 years.
expires = int(time.time()) + 365 * 24 * 3600 * 10
...

swift-code swift3/middleware.py:
...
delta = datetime.timedelta(seconds=60 * 10)
            if d1 - d2 > delta or d2 - d1 > delta:
                return get_err_response('RequestTimeTooSkewed')(env, start_response)
...

If i change the expires to the expected value it works. Should this value be configurable, or is this an swift3-bug/feature?

Thanks
Tino
