DateAndTime::Timer Property

Returns a Double value representing the number of seconds elapsed since midnight.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public:
static property double Timer {
	double get ();
}

Property Value

Type: System::Double
Returns a Double value representing the number of seconds elapsed since midnight.

The Timer property returns both the seconds and the milliseconds since the most recent midnight. The seconds are in the integral part of the return value, and the milliseconds are in the fractional part.

This example uses the Timer property to pause the application. It can perform other processing during the pause.

Public Sub waitFiveSeconds()
    If TimeOfDay >= #11:59:55 PM# Then
        MsgBox("The current time is within 5 seconds of midnight" & 
            vbCrLf & "The timer returns to 0.0 at midnight")
        Return 
    End If 
    Dim start, finish, totalTime As Double 
    If (MsgBox("Press Yes to pause for 5 seconds", MsgBoxStyle.YesNo)) =
         MsgBoxResult.Yes Then

        start = Microsoft.VisualBasic.DateAndTime.Timer
        ' Set end time for 5-second duration.
        finish = start + 5.0
        Do While Microsoft.VisualBasic.DateAndTime.Timer < finish
        ' Do other processing while waiting for 5 seconds to elapse. 
        Loop
        totalTime = Microsoft.VisualBasic.DateAndTime.Timer - start
        MsgBox("Paused for " & totalTime & " seconds")
    End If 
End Sub

Note that you must qualify the Timer property with the Microsoft.VisualBasic namespace, because Timer is also a defined class in the System.Threading, System.Timers, and System.Windows.Forms namespaces.
