I was just thinking about time-zones and daylight savings & how to find out what time it is somewhere now you need to find an online map. Then my mind moved to how people used to determined the day from when dawn was. Then I thought, since we know the rotation of the earth round the sun, we can work out dawn for all longitudes and latitudes, so we should now be able to make clocks where we just type in our long and lat and then it could give us our day based on dawn and sunset D:0:00 would be dawn, D:1:00 would be one hour after dawn N:0:00 would be sunset, and so on...the number of hours etc for each would vary over the year, but you could always start work x hours after sunrise and work for y hours. No more need for daylight saving.
Since we have online maps telling us the what time it is everywhere else, we could still use these to tell us whether we could contact people easily. Or even better, instead of standard clocks, we'd have plasma display screens showing us our daylight time with a list down the side of other places we were interested in for quick reference.
This can't be an original idea, off to google.

"Lunchtime doubly so". The closest I had was a GPS navigation system that automatically switched between day and night mode at sunrise/sunset, calculated by your exact Global Position.
