  AWS::Events::Rule ScheduleExpression: "cron(* 1 * * * *)" 
  *cfn-lint version: (cfn-lint 0.27.5)*
  
  *Description of issue.*
  
  ```
    EventRule:
      Type: "AWS::Events::Rule"
      Properties:
        ScheduleExpression: "cron(* 1 * * * *)" 
        State: "ENABLED"
        Targets:
          - Arn: !Ref Foo
            Id: "Foo"
            RoleArn: !GetAtt FooArn.Arn
  ```
  
  Check should be probably in:
  
  [src/cfnlint/rules/resources/events/RuleScheduleExpression.py](https://github.com/aws-cloudformation/cfn-python-lint/blob/master/src/cfnlint/rules/resources/events/RuleScheduleExpression.py)
  
  The above `ScheduleExpression` is invalid (need a value for minute if hour is set). For example `cron(0 1 * * ? *)`
