Time shows in formula result when time is not selected

Likely a simple solution for this.
I have a table called “Event” where the primary field is pulling the date from a secondary field called “EventDate”, adding a number from a field called “OrderInDay”, and then adding an autonumber from a field called “EventID”.

I do not have the time showing in the date field.

The issue is that the result in the primary field does include time.

Here are the values in the three fields.

EventDate: 2018-03-18

OrderInDay: 1

EventID: 3

And this is the result: 2018-03-18T00:00:00.000Z (1)-ID3

Here is the formula in the primary field: {EventDate} & " (" & {OrderInDay} & “)-ID” & {EventID}

I’m new. What am I missing here?

Thanks.
