Amazon: Allows specific access using MFA within specific dates

This example shows how you might create an identity-based policy that uses multiple conditions, which are evaluated using a logical AND. It allows full access to the service named SERVICE-NAME-1, and access to the ACTION-NAME-A and ACTION-NAME-B actions in the service named SERVICE-NAME-2. These actions are allowed only when the user is authenticated using multifactor authentication (MFA). Access is restricted to actions that occur between July 1, 2017 and December 31, 2017 (UTC), inclusive. This policy grants the permissions necessary to complete this action programmatically from the Amazon API or Amazon CLI. To use this policy, replace the italicized placeholder text in the example policy with your own information. Then, follow the directions in create a policy or edit a policy.
