Lot of things changing on the root rot front. First, the old (that is, mid-90's publication date) guidance to cut all infected trees plus a buffer of 50'-75' is going by the wayside because this ends up often creating small clear-cut openings in places where a thin was intended. The new guidance (word-of-mouth only, not yet published) is to leave surviving trees in these patches and only take the dead ones. This allows the possibility of capitalizing on the genetics of trees resistant to the pathogen. Second, the phylogenetics guys have changed the name of the thing. The laminated root rot that affects trees in the Pine family is now called Phellinus sulphurascens and the old name, P. weirii, goes to the variety that affects trees in the Cypress family, including the redcedars. The shoestring rot, formerly known as Armillaria mellea or A. ostoyae, is now known as A. solipides. White speck rot, formerly known as Fomes pini, is now known as Phellinus pini. It drives me nuts when they change the Latin names of things because it takes years to propagate down through all of the texts and for everybody to learn and recognize them all.
As for daytime vs nighttime, my guess is that the officials there figure that if you're awake you can hear and dodge a falling tree, but you can't if you're asleep.
