Current behavior On a calendar with a time picker once you select a time by clicking on one of the time picker arrows it then begins to select a value when the user hovers over any of the time picker arrows.

Expected behavior On a calendar with a timepicker once you select a time by clicking on one of the time picker arrows it will then not select a value when a user hovers one of the time picker arrows

Minimal reproduction of the problem with instructions

1. Click on any one of the time picker arrows in the provided stackblitz https://stackblitz.com/edit/primeng-calendar-show-time-mouseout-issue-k4v3hw - this will result in the counter displaying 1 change which is fine.
2. Hover over any one of the time picker arrows - this will result in the counter displaying 2 or more which is not expected as when the user is hovering over a time picker arrow it should not act as a select event.

Alternative This can also be replicated on the primeng website https://primefaces.org/primeng/#/calendar

1. Select the example calendar for time
2. Select any one of the time picker arrows.
3. Delete the input for time picker input field.
4. Hover mouse cursor over one of the time picker arrows What is the motivation / use case for changing the behavior? Hovering on any time picker arrow after selecting any of the time picker arrows once should not act as if the user selected it via click event. This is related to a previous ticket where hte issue was mitigated but not resolved https://github.com/primefaces/primeng/issues/8584

This bug also causes validators to fire several times a second if you use the component in a reactive form. This renders the timepicker completely unusable if you want to utilize async validators.

Just want to update that this is also reproducible on primeng v10 - can be seen in the website following the same steps as on v9 where it is still an issue

The calendar component implementation listens to a button "mouseout" event on the time picker buttons. When fired, the time is updated.

an example: in calendar.ts

<button class="p-link" type="button" 
    (keydown)="onContainerButtonKeydown($event)" 
    (keydown.enter)="incrementHour($event)" 
    (mousedown)="onTimePickerElementMouseDown($event, 0, 1)" 
    (mouseup)="onTimePickerElementMouseUp($event)" 
    (mouseout)="onTimePickerElementMouseOut($event)" 
    pRipple
>
    <span class="pi pi-chevron-up"></span>
</button>

The event fired updates the time and emits the model like so:

onTimePickerElementMouseOut(event: Event) {
    if (!this.disabled && this.timePickerTimer) {
        this.clearTimePickerTimer();
        this.updateTime();
    }
}
