Extracting time and date of appointment

Hello,

I'm creating a page template on the front end with the my_appointments shortcode.

I can see that the time of booking is displayed using $r->start.

This variable from the results array includes both the date and time. Is it possible to be able to extract the date and time separately, such as $r->date and $r->time? Is this possible or can you help me to achieve this?

Many thanks,
Steven
