We would make a jump back in time, where every town or country had it's own local time. Look for railroad timetables from the 1800's or 1900's.
Like many wrote it before in the various comments, it doesn't make sense.
In this synchronized world, it would be a nightmare to setup a meeting across timezones and shifted local times...
On top of this, you would instantly render a lot devices obsolete that are not synchronized with an external source, or which do not accept update timezone tables.
Just use the "KISS" principle = Keep It Simple, Stupid. One timezone, no DST....
