As 2D's points out, and I'll re-iterate. Instrument time is time flying "with sole reference to instruments".
That means - head in the cockpit, on the clocks, not looking outside because you can't see outside. No different when you were training and had a hood or foggles on.
Logging time on top, in VMC, as instrument time is an illegal logbook entry, and depending on which nation's licence you're flying on can be a criminal offence.
