UIComponent : date : showstime and validation : error "Please enter a valid date."

[tales-desde-mileto]

Preconditions (*)

1. Magento 2.4.4
2. Magento 2.4.3-p1

Steps to reproduce (*)

1. Define a ui_component form.xml

2. Add datetime UI component with: showsTime=true validation: validate-date=true

    <field name="prueba15_id">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                  <item name="label" xsi:type="string" translate="true">Prueba15</item>
                  <item name="formElement" xsi:type="string">date</item>
                  <item name="dataType" xsi:type="string">date</item>
                  <item name="options" xsi:type="array">
                          <item name="showsTime" xsi:type="boolean">true</item>
                   </item>
                   <item name="validation" xsi:type="array">
                          <item name="validate-date" xsi:type="boolean">true</item>
                   </item>
            </item>
        </argument>
    </field>
   

Expected result (*)

1. No error if date format is ok. But, always shows this error: "Please enter a valid date."

2. I have tested with differents parameters in config and always same error: validate-datetime, pickerDateTimeFormat, etc

3. I show that, perhaps, the problem is in this js function: Magento_Ui/js/form/element/date.js
   onShiftedValueChange: function (shiftedValue) {
   var value,
   formattedValue,
   momentValue;

   if (shiftedValue) {
   momentValue = moment(shiftedValue, this.pickerDateTimeFormat);

    if (this.options.showsTime && !this.options.timeOnly) {
        formattedValue = moment(momentValue).format(this.timezoneFormat);
        value = moment.tz(formattedValue, this.storeTimeZone).tz('UTC').toISOString();
    } else {
        value = momentValue.format(this.outputDateFormat);
    }
   

   } else {
   value = '';
   }

It gets the value on line:
value = moment.tz(formattedValue, this.storeTimeZone).tz('UTC').toISOString();

But when it check it in validation,
rules.js:
'validate-date': [
function (value, params, additionalParams) {
var test = moment(value, additionalParams.dateFormat);

value is like: '2022-02-28T16:08:00.000Z'
And additionalParams.dateFormat is = 'M/DD/YYYY'
Then, always error.

Actual result (*)

1. Always shows this error: "Please enter a valid date."
