Let say I have the two date/times:
6/4/2013 5:46:41 PM
6/4/2013 5:50:03 PM
=  3:22 seconds

6/4/2013 5:54:29 PM
6/4/2013 5:55:30 PM
= 0:59 seconds

How can I can calculate how many minutes and seconds between the two times?

        Dim d1 As Date = Date.Parse("6/4/2013 5:46:41 PM")
        Dim d2 As Date = Date.Parse("6/4/2013 6:50:03 PM")

        Dim ts As TimeSpan = d2.Subtract(d1)

        Dim s1 As String = ts.ToString  'hh:mm:ss
        Dim s2 As String = String.Format("{0}:{1}", Math.Floor(ts.TotalMinutes), ts.Seconds.ToString("00")) 'mm:ss

        MessageBox.Show(String.Format("{0}{1}{2}", s1, Environment.NewLine, s2))

Subtracting two dates in .NET yields a TimeSpan instance. You can interrogate the TotalSeconds property of that instance.

e.g.

Dim firstDate As DateTime = DateTime.Parse("6/4/2013 5:46:41 PM")
Dim secondDate As DateTime = DateTime.Parse("6/4/2013 5:50:03 PM")

Dim diff As TimeSpan = (secondDate - firstDate)

Console.WriteLine(diff.TotalSeconds)

hi.. you can try this

DateTime startTime = DateTime.Now;

DateTime endTime = DateTime.Now.AddSeconds( 75 );

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
Console.WriteLine( "Time Difference (hours): " + span.Hours );
Console.WriteLine( "Time Difference (days): " + span.Days );

Output Like,

Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0
0
