Describe the bug

I noticed two bugs:

• Selecting a day in the calendar resets the time to midnight.
• Setting a time with a day selected resets the day to undefined.

Expected behavior

I expected that :

• Selecting a day in the calendar does not affect the currently selected time.
• Setting a time in the field does not affect the currently selected date.

Context & Screenshots (if applicable)
