If the only problem with abolishing time zones is having to look up a table to know when to call someone, then perhaps it's better to abolish them. Most of the uses we make of international times don't have anything to do with timing phone calls.
To make a decision on what's best obviously needs a comprehensive look at all the pros and cons, not just one word-gamey one like this.
Perhaps the current set of time zones are not optimal. Maybe the best solution turns out to be just rearranging them. I would hope making them wider but perhaps there are biological reasons to refine them even further and make daylight savings even more complicated. If that somehow extends out lives, makes us more productive, or saves enough power (money), it might be worth the added cost to programmers (money).
Obviously, that lookup table is not the only problem with abolishing time zones, the giant problem is forcing billions of people to change their notion of when "9 to 5" happens, as well as every other activity that is pinned to a specific time through custom, culture, and language.
