Details of the scenario you tried and the problem that is occurring

When trying to create a KDS key, the error "String was not recognized as a valid DateTime" is thrown on machines with culture en-us and de-de.

Verbose logs showing the problem

        }
    }
}

These are the keys:

Most importantly, the EffectiveTime property is a DateTime object already. Why would you need to run the Parse method on a DateTime object?
