I think HOI had right time frame, but it should be 1936-1950. ISTM 2 weeks should the max time frame.
There is companion game for WiF called 'Days of decision' that enable you to play 1936 to 46. It brings in all the political wrangling you're looking for. It also allows for the ahistorical scenarios that frequently occur in HoI.
When you consider the impulses within each 2 month turn, a typical "turn" probably averages out to around two weeks. For example, the July-August time-frame can easily run 14 impulses. Think of that as 7 "turns" within a 2 month time period. That come out to a little more than week long turns. Of course the winter months have fewer impulses, but it averages out to the time frame you're looking for.
WiF will never have the level of detail found in WitP or HoI. The platforms are totally different. Yet, it is still the best strategy WWII wargame out there IMO.
