12 – Design devices to have an accurate time

How do you ensure that your device accurately determines UTC? A secure device should have a valid certificate. IoT devices use a server certificate to communicate to the cloud and the certificate presented uses time for certificate validity. Having reliable and accurate time is compulsory to be able to validate certificates. Because IoT data is not ordered, including an accurate timestamp with the data will enhance your analytic capabilities.

Follow the best practices and check if your workload is well-architected.
