How does a reminder that has both a location and time reminder work? I can add a reminder with both "Remind me on a day" and "Remind me at a location" turned on.

When I turn both on, how does the remind work? Is it:


only at the specified time if I arrive/leave the location
at the specific time or if I arrive/leave the location
something else?
The reminder alerts do not work in tandem. This means it will alert you:


At the exact date and time you have specified
AND when you enter/exit the specified geofence
