Yes, it's going to cause a lot of confusion and missed meetings. At the moment everyone says "pacific time", but now that will mean two different things.
replyI think we'll need to say Vancouver time or California time.
Maybe people will finally learn the difference between PST and PDT.
replyMountain time is ambiguous due to Arizona, and yet we still use that phrase. Hawaii-Aleutian time is also ambiguous: the Aleutian islands do daylight savings, but Hawaii doesn't.
replyCasual speech doesn't use the city names (like America/Los_Angeles for pacific time); presumably we'd have Pacific time (America/Los_Angeles) and BC time (an update of the existing America/Vancouver). If Washington's time change ever gets approved it would presumably become simply Washington time (America/Seattle maybe?).
