DateTime elapsed in c#?

Question

so I'm trying to display messages in a readOnly textbox, with the elapsed time and date, although I'm having some problems. It's displaying that the message was sent 325 days ago, when really it should be 1 min ago. Could someone please help to tell me what I've done wrong?

string[] date;
string[] messageArray = 
    File.ReadAllLines(Server.MapPath("~") + "/App_Data/messages.txt");

for (int i = 0; i < messageArray.Length; i++)
{
        date = messageArray[i].Split(' ');
        DateTime date1 = DateTime.Now;
        DateTime date2 = Convert.ToDateTime(messageArray[0]);
        TimeSpan timeDifference = date1.Subtract(date2);
        string formattedTime = "Sent " + timeDifference.Days + " days, " + 
         timeDifference.Hours + " hour/s," + 
         " and " + timeDifference.Minutes + " mins ago";

        File.AppendAllText(Server.MapPath("~") + 
              "/App_Data/messages.txt", "\n" + formattedTime + "\n");
        File.AppendAllText(Server.MapPath("~") + 
              "/App_Data/messages.txt", sendMessageTextBox.Text + 
              System.Environment.NewLine);

}

Please show value of `messageArray[0]`. (You don't really need the rest of the sample...) — Alexei Levenkov, Jun 03 '13 at 04:09
Side note: to format value there is `String.Format` which looks better than sequence of `+`. — Alexei Levenkov, Jun 03 '13 at 04:11

Running the below

        DateTime date2 = DateTime.Now;
        Thread.Sleep(1000);
        DateTime date1 = DateTime.Now;

        TimeSpan timeDifference = date1.Subtract(date2);
        Console.WriteLine(timeDifference.Seconds);

Show output of 1

Print the value in messageArray[0] to see if it contain what you think it contains

To express the net elapsed time in seconds, use timeDifference.TotalSeconds (total time expressed in seconds), rather than timeDifference.Seconds (which is the seconds component of the total time). – Guy May 15 '15 at 05:36
