if the camera's time is not sync to aws cloud, is that ok?

[pppaulpeter]

if not, i mean probably the aws authentification will failed, and how to solve this problem?

For images-to-aws-s3 I don't think there's a problem since the device is authenticated using an access token, but for telemetry-to-aws-iot-core there will probably be a problem if the clocks aren't synchronized.
