The button shows a calendar icon and today's date at 12:00. The popover has a month calendar and, under a divider, a field labeled Time.
Use one picker when a date and a time belong together, such as a deadline. A separate Input for the time is clearer if the calendar should close first. On Vue, Ark UI does not store the time on the date.

FAQ
Why doesn't the picker close when I pick a day?
closeOnSelect is false on DatePicker, so the time field stays reachable. Escape, a click outside or the button close it.
How does the time field work?
It's an Input with type="time", starting at 12:00 and updating its own value on change. The browser draws the hours and minutes and formats them in the user's locale.
Is the time stored with the date?
No: the date is the picker's value and the time is a string such as 14:30. Combine them when you submit, for example into an ISO date-time.
What does the button say?
The date in long form followed by at and the time, or Pick a date and time when no date is selected. The button prints the value itself, formatted with Intl.DateTimeFormat, so the text needs no date library.
