Answer 1

I think the problem is that writing out the last update time into a hidden field like that will just do a ToString on the date which by default won't render out the milliseconds. You could try rendering out the timestamp as some absolute value such as ticks:

<%= Html.Hidden("LastUpdate", Model.LastUpdate.Ticks) %>

You can then reconstruct your datetime on the other side by converting the value back into a long & reconstructing the DateTime:

var dt = new DateTime(Int64.Parse(ticks));
