#### Common information available in all requests

- `aws:CurrentTime` - This can be used for conditions that check the date and time.
- `aws:EpochTime` - This is the date in epoch or Unix time, for use with date/time conditions.
- `aws:PrincipalType` - This value indicates whether the principal is an account (Root credential), user (MinIO user), or assumed role (STS)
