You have to add the ticks to an existing date. What are you using at your token date?

Here is what I was thinking:
        Dim tokenDate As Date = Date.Parse("1/1/1900")
        Dim result As Long

        'This is the value you would want to store
        result = Date.Now.Subtract(tokenDate).TotalSeconds

        'Convert the stored value back to a date
        MsgBox(tokenDate.AddSeconds(result))
Make sure you store your result as Long (Int64) otherwise you will get an overflow error.
