Issue running command [gcloud app logs read].

What steps will reproduce the problem?
I'm encountering an error that I've never seen before when I run "gcloud app logs read" after deploying my app using "gcloud app deploy".

What is the expected output? What do you see instead?
This is the error message shown: ERROR: gcloud crashed (ValueError): time data '2016-09-18T12:19:50Z' does not match format '%Y-%m-%dT%H:%M:%S.%fZ'

Please provide any additional information below.
