Like the previous poster, I have dyscalculia, and have huge problems with time. I've got better with age, because I've learned more effective strategies to deal with, so I'm generally on time for most things these days, but it's taken 20 years of effort to get to that stage, and and I still have to put in a lot of effort on an everyday basis.
Do they have a job?
Yes, but it pays just above living wage although I have a postgraduate degree.
Do they ever go to appointments?
Yes. Sometimes I miss them. If it's unmissable, I spend hours planning how to do it. If it's a regular journey (to school, to work etc) I can get a routine that works, and that point, I'm usually fine. One-off events are a lot more hit and miss.
Do they have children?
Yes. You don't need to be able to tell the time to be a parent. My kids perceive time the normal way.
Do they ever cook?
Yes. I'm a very good cook. I don't use time cues, but things like colour and texture and smell to know when the food is ready. I bought a rice cooker with a keep warm function recently, which was a life-changer.
I avoid making appointments where possible, and often socialize by inviting friends over for a meal etc, where I don't have to be on time, because that way everyone is happy. I pass as being normal but a bit ditzy so most people don't know how much effort I have to put in to normal things like being on time or doing a timed task, or checking finances, or writing down numbers, or working out what order to do things in.
