One the biggest arguments for dumping the time switch is the difficulty caused by inconsistent switching between North America and Europe. That's a one hour change that everyone knows about well in advance. I'm not sure how those companies are supposed to coordinate anything if all meeting times are now relative to when the sun rises in each employee's location.
They are already relative to when the sun rises in each location. People generally try not to schedule meetings when it's going to be the middle of the night for the other party.
I'm not saying we should do away with the entire system of timekeeping. Just adjust work and school start/stop times to be better synced up with natural daylight.
