Hi,

This should get you started, now sure how accurate it will be, logic dictates that BST/GMT will be a problem, but it should let you convert a timezone.

Code behind

Imports Microsoft.Win32
Partial Class _Default
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim regTimeZone As RegistryKey = Nothing

Dim strTimezone As String = ""
Dim intInteger As Integer = 0
If Not Page.IsPostBack Then
regTimeZone = Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones")
For Each strTimezone In regTimeZone.GetSubKeyNames
ddlTimeZones.Items.Add(New ListItem(regTimeZone.OpenSubKey(strTimezone).GetValue("Display"), -BitConverter.ToInt32(regTimeZone.OpenSubKey(strTimezone).GetValue("TZI"), 0)))
Next

End If

End Sub
Protected Sub cmdConvert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdConvert.ClickDim dtmNow As DateTime = New DateTime(Date.Now.Year, Date.Now.Month, Date.Now.Day, txtTime.Text.Split(":")(0), txtTime.Text.Split(":")(1), 0)
dtmNow = dtmNow.AddMinutes(ddlTimeZones.SelectedValue)

litResult.Text = dtmNow.ToString("F")
End Sub
End Class

Markup

</head>
<body>

<form id="form1" runat="server">

<div id="div1">

Time:  &nbsp<asp:TextBox runat="server" ID="txtTime" ></asp:TextBox><br />
Time Zone:   <asp:DropDownList runat="server" ID="ddlTimeZones">

</asp:DropDownList><br />

<asp:button runat="server" ID="cmdConvert" Text="Convert" /><br />

Result:   <asp:Literal runat="server" ID="litResult" ></asp:Literal>

</div>
</form>
</body>

</html>

Give it a try.
