astimezone() cannot be applied to a naive datetime

[jumping]

When I run the following command, I got error message: astimezone() cannot be applied to a naive datetime.

$aws cloudwatch get-metric-statistics --metric-name CPUUtilization --start-time 2014-10-28T23:18:00 --end-time 2014-10-31T23:18:00 --period 3600 --namespace AWS/EC2 --statistics Maximum --dimensions Name=InstanceId,Value=i-80efb86d

Version

$aws --version
aws-cli/1.5.4 Python/2.7.6 Darwin/14.0.0

HI.
Hi. same issue.

aws --version
aws-cli/1.5.5 Python/2.6.9 Linux/3.4.68-59.97.amzn1.x86_64

But

aws cloudwatch get-metric-statistics --metric-name CPUUtilization --start-time 2014-11-04T00:00:00Z --end-time 2014-11-04T23:59:59Z --period 3600 --namespace AWS/EC2 --statistics Maximum --dimensions Name=InstanceId,Value=i-XXXXXX

OK

This issue timestamps need a 'Z' on the end for the options '--start-time' and '--end-time.
