this is fairly accurate, I'd say.
space cadets about time, and projecting poor self bias. The latter's also applicable to other types, though.
I'm aware how terrible with time I am, so I often try to see in advance what the other party expects of me to reduce potential for conflict.
What's funny to me is that if I ask an ISFJ about what time they're doing something [like I have a reason for it/cuz I'm working around their needs].. they'll
describe the time vs actually give me a time. Not sure if all ISFJs do this, but my mother & my ex did it [an ESFJ friend did this too, occasionally].
Simplest example: I was often asked to set the autostart on the coffeemaker for the mornings. 6am on weekdays, but variable on weekends.
So I'd ask: "around what time are you getting up tomorrow? I'm setting the coffee"
ISFJ: Oh. Early.

Me: ok, but what time do you want it to start?
ISFJ: Early is fine.
Me: EARLY is not a time I can program on the coffeemaker.. ffs.
ISFJ: why are you annoyed?
Another point comes to mind when the descriptions of time get skewed.
My ISFJ ex, I'd call in advance while on break at theatre rehearsals to let him know it was running far later than 9pm. He'd say, "that's fine, just show up when you're out.." Then he'd be mad I'd show up after midnight without calling again. I guess his estimate of "far later than 9pm" was like 10:30/11pm. We had frustrating holes in our communication like that, but nothing too terrible.
