Day time is just a number, with no inherent meaning. Yes, 12 and 0 are special times, but all the rest shrinks and grows with the seasons. Is 7 too early to be in office, is 11 too late?

My point is, how about we stick to the time switching, since a large scale agreement (LSA) seems impossible, and focus on small scale agreements (SSA)? We could make the SSAs so to exactly cancel out the negative impacts from the LSA.

For example, office hours (a SSA) can make the inverse switch so that employees don't have to change their schedule in practice. Your clock is one hour early for the next six months? Who cares, just come to office an hour late for the same period. For some teams with flexible times this would hardly be noticable.

This idea apparently has some flaws because I haven't seen a grocery store with different opening times for winter and summer. Or maybe they just change the whole display twice a year so I never notice.

Anyways, fire away and tell me what's wrong about this approach.
