How do I ensure that a historical viv.time.DateTimeExpression does not affect any similar subsequent utterances in the same conversation?

In order to ensure that Bixby does not use any historical input, the relevant concept(s) should be marked as transient.

viv.time.DateTimeExpression can be made transient in the following way:

structure (CustomDateTimeExpression) {
 role-of (viv.time.DateTimeExpression)
 description (wrapper for DateTimeExpression)
 features {
 transient
 }
}

A sample capsule is attached showing that the DatetimeExpression is not carried over between utterances in the same conversation.

To trigger the behavior,

1. Use the utterance, "What's happening tomorrow?" This will result in a CustomDateTimeExpression being shown.
2. Use the utterance, "What's happening?" This will result in a computedDateTimeExpression. Since it is enclosed within an if/else block, computedDateTimeExpression can only be displayed if the CustomDateTimeExpression does not exist. If CustomDateTimeExpression was not marked as transient, this part of the if/else block would not be triggered.
