Input form Date

Input form Date

Hello,

Is it possible on an input form to take the calendar start date that user inputs, and make that the timestamp for all of the variables submitted through that form? 

For instance, if I chose to submit 6/27/2023 in my calendar input and submitted it today it would show in my "Date & Time" column 6/29/2023 when I really want it to show 6/27/2023.
