How do I get GOOGLEFINANCE to return only the date and not the date and time of stock price history?

=GOOGLEFINANCE("NASDAQ:GOOGL","close",date(2021,1,1),today(),1)

returns closing history in two columns "Date" and "Close" since Jan. 1, 2021. The date column displays date and time values:

1/4/2021 16:00:001/5/2021 16:00:001/6/2021 16:00:001/7/2021 16:00:00

How do I modify the formula to return only the date and not the time?

1/4/20211/5/20211/6/20211/7/2021
