DateTimePicker assign default time

[yhranik-vp]

I am using two DateTimePicker components to build a date + time range selector.

When you click on a date in the calendar, the time is always set to "00:00." For the end date selection, I would like to set it to "23:59" by default.

Proposal: Provide an optional prop for the DateTimePicker component that allows assigning a default time upon date selection.
