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.
To learn about using multiple conditions within the Condition block of an IAM
    policy, see Multiple values in a condition.
