Strange Thought (or predictability of daylight)

Night and day and all the seasons become completely random.

It must be some crazy astrophysics thing but the weird part is that all of nature is about the same, the only difference is that you wouldn't know if in 12 hours it was going to be 100 degrees or 10 degrees, it could be night or day at any point.

I took physics and do know this couldn't happen.  But lets just pretend.

What would people do if they didn't know how long the day was going to be?  I think about the daylight savings days that seem so long, and that is only and hour a day.

I think that people would set up clocks, large giant clocks that can be seen through the towns so everyone knows what time it is no matter what is going on outside.

I wonder if that would make things more productive, because when it is nice out you may only have those 12 hours of nice weather to work outside.

It is a strange thought I guess but, doesn't everything now seem so predetermined...
