Just the opposite. It is considering the time. But that's not your only issue. Your SUMIFS says to add up all unit prices where the SKU (Table 1::B) = 6/26/24 at 12:00AM and the payment method is cash. So it is attempting to sum up the unit prices, not the actual sales/totals, and is comparing the SKU to a date.
To add up the totals for the date, regardless of the time, you need to check that the date&time is greater than or equal to the specified date at 12AM and also less than the next day at 12AM.
Formula in C2 =SUMIFS(Table 1::G,Table 1::A,">="&A2,Table 1::A,"<"&A2+1,Table 1::I,"Cash")
I did not recreate your table and test this formula. I hope I got it right.
Make sure you don't put a time other than 12AM in cell A2 or the rest of the column. If you simply type the date and no time, it will be 12AM. Format the column to not show the time.
