It's usually not a matter of "fixing" the phase in the sense of being more in phase, (100% phase alignment is mono) but of adjusting the tone to taste.
Also needing to set up the mikes "right" in the first place is a big part of the advantage of time delay tweaks. It gives you more mike positioning flexibility.
For example say you set up a pair of spaced mikes and start playing listening back live through headphones and you find that a little bit of a body turn or
move to the right or left rather than straight on or in the middle improves the sound, or that you want one mike in a little closer for a particular sound and
the other mike further out for another sound, or some other thing like over the shoulder mic'ing of one of the mikes.
