Answer 1

Try this:

if(item.logout.HasValue) {
    item.logoutTime = item.logout.Value;
}

Answer 2

You're trying to check if a conversion against the null object is null rather than checking the nullable object itself. You need to change this line:

item.logoutTime = (item.logout.Value.ToShortDateString() != null) ? item.logout.Value.ToShortDateString() : "-";

to

item.logoutTime = item.logout.HasValue ? item.logout.Value.ToShortDateString() : "-";
