DatePicker: Add range selection support with time

1) Environment

• PrimeFaces version: 7.0.5
• Does it work on the newest released PrimeFaces version? No
• Does it work on the newest sources in GitHub? No
• Application server + version: WildFly 17
• Affected browsers: All

2) Expected behavior

When selectionMode = ‘range’ and showTime = ‘true’ there should be two timepickers visible to be able to select a time selection within a day or over multiple days.

3) Actual behavior

There is only one timepicker which sets the time on both start and end date. I can’t think of any practical usecase why someone would like to do that. So I can think the new behaviour can be the default behaviour.

4) Steps to reproduce

Create the sample XHTML

5) Sample XHTML

<p:datePicker selectionMode="range" showTime="true"/>
<p:datePicker selectionMode="range" timeOnly="true"/>

6) Sample bean

No bean required

To be honest, I have no idea on how the UI should look like for this feature. I don’t think we can easily recycle the single date time picker.
