Dates in my spreadsheets keep getting converted to DateTimes and I want the time component removed as this is handled in a differnt column

Question

I keep track of trading data in a private spreadsheet and, once a trade is closed, I push a button to run some AppsScript to copy the data across to a publicly visible spreadsheet. It all works well except the following point. I put the dates and times a trade is opened in two different columns and the same with the dates and times trades are closed. When I copy the dates across to the target spreadsheet, instead of "10 Jul 2022" it is showing as "10/07/2022 02:00:00". When I sort the spreadsheet on these date and time columns, this can often produce unwated results. What I want is for the date column to just display as "10 Jul 2022" and for that data to recognized as a date for sorting purposes. Is that possible?

function updatePublicSheet(){
  var coinBought;
  var dateBought;
  var timeBought;
  var priceBought;
  var dateSold;
  var timeSold;
  var priceSold;
  var sLrIndex; 
  var tLrIndex;
  var sss = SpreadsheetApp.openByUrl("https://docs.google.com/spreadsheets/d/1cBGpD0nUqCGtQqq78svw4fxA4ZgwBqV2yzIbgY1tY2o/edit#gid=1107419239"); 
  var sSheet = sss.getSheetByName('SS Open Trades');
  var sRng = sSheet.getRange("H3:J").getValues();

  // Find last entry in columns H, I or J in the Open Trades sheet
  for (var i = sRng.length-1;i>=0;i--){
    var sLrIndex = i;
      if (!sRng[i].every(function(c){return c == "";})){
        break;
      }
    }

    Logger.log("Last source row is %s", sLrIndex + 3);

    // Check that the closed information has been added to all columns
    // index 8 = 8th column = H = dateSold
    // index 9 = 9th column = I = timeSold
    // index 10 = 10th column = J = priceSold

   if ((sSheet.getRange((sLrIndex + 3),8).getValue().length) == 0 ||
      (sSheet.getRange((sLrIndex + 3),9).getValue().length) == 0 ||

        SpreadsheetApp.getUi().alert("You cannot process partially completed entries");
        return;
      }
