populating a combobox with just a date not time from a select query to pass as a varaible into a query

access 2010.
userform
I have a combo box being populated from the below sql statement...below  "rowsource"
SELECT DISTINCT [dbo_t_dispensing_email_audit_history].[Notify_Processed_Date] FROM dbo_t_dispensing_email_audit_history ORDER BY [Notify_Processed_Date];

What I need:
The value being pulled includes a time stamp value such as
6/5/2015 1:21:36 PM

I need the value in the combo box to display just the DISTINCT DATES and NOT THE TIME ALONG WITH IT ?

Thanks
