The advent of daylight savings time had me thinking about something that's always puzzled me.
Why is it when you set your clock back in the fall, you go from 3 to 2. But when you move a meeting back you go from 2 to 3?
And when you move your clock up, you go from 2 to 3, but when you push an appointment up, you move it from 3 to 2?
When you say "back" you generally think later, but sometimes you mean "earlier".
The same kind of thing can apply when you cross a time zone. I've had arguments with people who ask "which way do I set my watch" and I say, "we just went back an hour" but they say "no, I need to move it up an hour", but we're really thinking the same thing. We both moved our watch from 2pm to 1pm because we travelled west over a time line.
Or am I completely insane? (ok, don't answer that)
