The problem that people are trying to solve by abolishing time zones is the annoying need to deal with time differences when scheduling meetings. No, abolishing time zones and DST would also remove huge swathes of code in all of today's operating systems, numerous costly bugs, and make time unambiguous without qualifiers like time zone or location. There are lots of reasons to do it. As others have pointed out, the real fundamental problem is best solved by people indicating their status somehow now and in the future, because not everyone in a country works 9-5, not everyone is available all of that time for phone calls, and why should everyone work to the same schedule anyway? If you want to schedule calls, use a calendar, if you want to make a call right now, use an availability indicator.
