Question

I am populating a data grid view in my program from an SQLite3 database which contains a date column using the code below

This date column is stored in Unix time and I want to display it obviously as a normal date

Is there a way I can do this as I’m reading the database into the data grid view?

SQLiteConnectionStringBuilder csb = new SQLiteConnectionStringBuilder();
csb.DataSource = Path.Combine(connectionPath, "sms.db");

SQLiteConnection connection = new SQLiteConnection(csb.ConnectionString);
connection.Open();

// SQL query to read the data fromt he database
SQLiteCommand command = connection.CreateCommand();
//Read Everything
string query = "SELECT * FROM message";

command.CommandText = query;

SQLiteDataAdapter dataAdaptor = new SQLiteDataAdapter(command);
DataSet dataset = new DataSet();
dataAdaptor.Fill(dataset, "Messages");
// Get the table from the data set
DataTable datatable = dataset.Tables["Messages"];

dataGridSMS.DataSource = datatable;

Answer 1

// This is an example of a UNIX timestamp for the date/time
double timestamp = 1116641532;

// First make a System.DateTime equivalent to the UNIX Epoch.
System.DateTime dateTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0);

// Add the number of seconds in UNIX timestamp to be converted.
dateTime = dateTime.AddSeconds(timestamp).ToLocalTime();
