Do we have a "sense of time"? I ask because upon reflection, it seems that I have to get back to my sentinels and time tracking devices constantly to know where I am in time. What day is it? What's the current time? I comprehend time ordering, cause and effect, but I can't measure nor track time worth a damn. If I go on holiday and avoid reference a watch and calendar, I can easily lose track in short order.
I'm not blind, nor deaf. I have a family and have never been isolated. I just assumed this is How Things Are, that attention must be paid in an effort to stay "in sync."
I found with the right schedule I would generally wake up 10 minutes before my alarm when off even when it was still dark outside. I can often guess what time it is +/-10 minutes throughout the day. I even stopped using a watch at collage as my internal clock was enough to get to class on time.
Granted, I was keeping a vary regular schedule and there where plenty of clocks around which helped, but I think most people can probably get to that level of precision.
In general humans have a sense of time. This is why the graveyard shift is so incomprehensibly difficult for human beings. At the core humans require routine but beyond that thoughtful activities lend themselves to daylight.
Depression is also strongly related to being in the dark, probably linked to us needing vitamin D.
