Metro pilot's (no auto-pilot) should be logging instrument time form wheels up to touchdown.
Leatherdog, from this statement, I would say you don't quite understand what instrument time is.
... unless you are in cloud you cannot log IF ...
neville_nobody, that is not quite correct. You need to be in IMC to log IF - which does not necessarily mean you must be in cloud.
Howard Hughes said basically this - but with better wording than I can manage at the moment.
... how about a clear night with little to no ambient light out in the middle of nowhere. I know in such conditions I am flying by sole reference to instruments!
Yes, indeed you are - and you may also be, technically, in VMC at the time. My feeling on this one, however, is that
you are not in VMC unless you can see that you are in VMC. Therefore, you should log this as IF.
