All you need to do is to change the display format for your column.
JMP date/time values are a numeric value of the number of seconds since 12 AM Jan 1, 1904.
Therefore, JMP's numeric value for 01/07/2025 12:00:00 AM is the same as the numeric value of 01/07/2025
withTime = informat("01/07/2025 12:00:00 AM","m/d/y h:m:s");
show(format(withTime,"fixed dec",12,2));
onlyDate = informat("01/07/2025","m/d/y");
show(format(onlyDate,"fixed dec",12,2));
Format(withTime, "fixed dec", 12, 2) = "3819052800.0";
Format(onlyDate, "fixed dec", 12, 2) = "3819052800.0";
Just change the format of the column to m/d/y and you will have what you want.
