DateTime issue when hour is >11

I’m working on a custom date format converter and everything seems to work fine until I get an hour > 11. Currently we’re using 24-hour format but I get the same behavior when I revert to 12 hr format using the long time converter. As as the hour reaches noon it formats 12 hrs behind.

public static string DateFormatConverter(string date)
{
    DateTime result = DateTime.ParseExact(date, "yyyyMMddhhmmss", null);
  
    string month = result.ToLongDateString().Replace(DateTime.Now.DayOfWeek + ",", "");
    month = month.Replace(DateTime.Now.Year.ToString(), "");
    month = month.Replace(DateTime.Now.Day.ToString() + ",", "");
     date = result.Day.ToString() + " " + month + result.ToString("yy") + " " + result.ToString("HH:mm:ss");
    date = date.Replace("  ", " ");
    return date;
}

>Solution :

See the docs, hh is for 12 hour format, you need HH for 24 hour format
