Date/Time Picker Clear Values

I have noticed that when clearing the values from a date/time picker, the data is still present in the data model even if it is cleared out of the field by the user. Is this expected behavior? If so, any tips on how to clear the model when the value is cleared from the field by the user? I’d prefer to avoid adding a “clear” button but this is my only idea so far.

My picker is below:

{
            "dateTimePickerOptions": {
                "format": "MM/DD/YYYY",
                "icons": {
                    "today": "fa fa-star"
                },
                "showTodayButton": true
            },
            "format": "MM/DD/YYYY",
            "label": "<strong>Start Date</strong>",
            "model": "form.exp.startDate",
            "onChanged_actions": [{
                "action": "function",
                "function": "model.state.reminderCalculated = false;"
            }, {
                "action": "namedAction",
                "name": "calcTestStartedStopped"
            }, {
                "action": "namedAction",
                "name": "setReminderMessageAndFields"
            }],
            "required": false,
            "styleClasses": "col-md-6",
            "type": "dateTimePicker",
            "visible_calc": "model.env.show.fields.startDate"
        }

I found some options for the picker that can help solve this. A few options, posted for anyone else who is looking to customize the picker:

"dateTimePickerOptions": {
                "format": "dddd MMMM Do YYYY",
                "icons": {
                    "today": "fa fa-star"
                },
                "showTodayButton": true,
                "showClose": true,
                "showClear": true,
                "maxDate": "12/01/2021",
                "useCurrent": true,
                "allowInputToggle": true
            }

Hopefully this is helpful to someone else with this issue in the future!
