Calculating number of seconds given two times

Hello,

I need to know how I can calculate the number of seconds between two
time stamps, e.g. if I have the following (using ToLongTimeString)

8:28:21 PM

and

9:02:33 PM

How can I find out the number of seconds elapsed between the two
times?

Look at the TimeSpan example:

(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
If Not IsPostBack Then
viewstate("starttime") = Now
Else
Dim tmspan As TimeSpan
tmspan = Date.Now.Subtract _
(CType(viewstate("starttime"), DateTime))
Label1.Text = tmspan.TotalSeconds.ToString
End If
End Sub

Re: Calculating number of seconds given two times

I'll presume that you have both times as DateTime objects. If not, you'll need to parse them and then call the Subtract method to get a TimeSpan object.

TimeSpan span = dt.Subtract(dt2);
int seconds = span.Seconds;
