Can't import time with dartetime from spreadsheet

I am trying to import a CSV that has a timestamp. However, every time I import it, I only get a date imported and time is left out.
As shown below I have the timestamps there.
I tried a Zapier import in the past and I saw that was the format to get datetimes, but it’s not reading mine.

What format does my CSV need to have to include time in the datetime column?
