People with ADHD are said to have "time-blindness".
In my case, I am both obsessed with it and oblivious to it.
My obsession comes from knowing that I can't trust myself to have an accurate sense of how time passes.
My obliviousness comes from not being able to see time as a resource that can be allocated. There is only now.
The past is any period of time between 10 minutes ago to 10 years ago.
The future is an infinite pool of time that I have to wait for when the NOW is over.
Any event that is in the future comes to represent the entirety of the future, and if I have to wait for it then it is very difficult for me to percieve replaces the now and I can't focus on anything.
