Wiz - I think this must be some sort of cognitive thing. I used to never be late. Now, it's like I have no concept of time (like how much time has passed or my judgement of time is off) and am almost always late.

It drives DDs crazy. It takes me about 1/2 hour tops to get ready to go anywhere, shower, hair, make-up, get dressed, etc. and I plan for that. But, I don't know what happens that I'm not "ready" when it's time to leave.
So, I don't have any ideas or suggestions because I seem to be having the same issue. I'll look at my neuropsych results and see if it says anything that would relate to this. I never put the two together until I saw your thread. I thought it was just something with me but now you have me thinking. If I find something, I'll let you know.
