No on the timezone deletion. While I support the ISO Date and 24 hour clock, doing away with timezones adds confusion and accomplishes little.
People generally live their lives within the local sphere. There is a lot said in the phase "My plane lands at Narita at 13:00/1PM" that isn't said in the phrase "My plane lands at Narita at 05:00 GMT".
With the first, I know that the locals are just finishing lunch, it's likely to be the warmest part of the day, and that it'll be busy getting to the hotel, but everything should be open.
Converting everyone to GMT means that every time you leave your region, you need to figure out what time customary activities take place - and you need to do this for every single different place you visit.
Standardized GMT doesn't work unless you are a hermit with no friends or need for communication.
