Default Gridview, Eval and Current Time

Please help me, I have a mental block on this one.

I have a field in a table identifying the difference for each country between their local time and GMT.

I would like to display in a gridview templated control the current time plus the adjustment for GMT difference to show the current local time.

Can anyone help?

As per your requirement as I tried to understand, you have the difference from each country against their local time and GMT already in the table right. So you could try and achieve the same using an SQL query, by adding/substracting the time as per the location.

I'm re-visiting this an have ended up with the following

In the Gridview I have:

<asp:TemplateField HeaderText="Local" SortExpression="BranchGMT">
     <asp:Label ID="Label1" runat="server" Text='<%# Eval("BranchGMT", LocalTime("BranchGMT")) %>'></asp:Label>

I have created a function

    Protected Function LocalTime(ByVal GMTDiff As String) As String
        Dim CurrentTime As Date = Now()
        Dim LT As Date
        Dim GMT As Integer
        GMT = CInt(GMTDiff)
        LT = CurrentTime.AddHours(GMT)
        Return LT
    End Function

When I run this it doesn't send the value of the BranchGMT field to GMTDiff (it goes across as "BranchGMT" and not the value).

Can anyone let me know what I need to do to send the correct value to the function please?

It works now just by using:

<asp:Label ID="Label1" runat="server" Text='<%# Eval("BranchGMT", LocalTime(Container.DataItem("BranchGMT"))) %>'></asp:Label>

instead of
<asp:Label ID="Label1" runat="server" Text='<%# Eval("BranchGMT", LocalTime("BranchGMT")) %>'></asp:Label>


Mental block is now cleared, I'm just waiting for the hair to grow back now!
