Once you retrieve it use following code
string yourDate = "10/15/2012 02:07:42 PM";
DateTime datetime = DateTime.ParseExact(yourDate, "MM/dd/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture);
string formattedDate = datetime.ToString("dd/MM/yyyy hh:mm:ss tt");
Dont forget to add using System.Globalization namespace!
Hope that helps. If it does, mark it as answer/upvote.
