Solution 1

You are trying to instantiate a DateTime object with string. It should be:

VB

If Not Value5 = "" Then
    Dim time As DateTime = Convert.ToDateTime(Value5)
    Dim format As String = "MMM d, yyyy HH:mm"
    Value5 = time.ToString(format)
End If

Look at MSDN documentation:

Solution 2

use this:

C#

var Value5 = string.Format("{0:MMM d, yyyy HH:mm:ss}", time);

this work just fine.
in .ToString() method you set the culture not format!

If I understand correctly, the problem isn't to convert a DateTime value to a String one but a String to a String formatted with another DateTime format.

I found that the problem is in the abbreviated month name.

So if you try the follow code I think you'll solve the problem:

VB

Sub Main()

    Dim Value5 As String = "Sept 21, 2009 21:18:55"

    Dim ci As New CultureInfo("en-us", False)
    Dim dtfi As DateTimeFormatInfo = ci.DateTimeFormat

    ' This are the default abbreviated month names that cause the problem
    'dtfi.AbbreviatedMonthNames = {"Gen", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec", ""}

    ' Try the follow updated ...
    dtfi.AbbreviatedMonthNames = {"Gen", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sept", "Oct", "Nov", "Dec", ""}

    If Not Value5 = "" Then

        Dim time As DateTime = Convert.ToDateTime(Value5, dtfi)

        Dim format As String = "MMM d, yyyy HH:mm"
        Value5 = time.ToString(format)

    End If

    Console.WriteLine(Value5)

    Console.ReadLine()

End Sub

I hope I was helpful
