Its already time to use a global time and stop with this bs of timezones. Timezones are an unreliable way to measure time the relation between time space
Time zones exist because the Earth is roughly spherical. Going to global time does not change this, and so does not remove the need for time zones.
Work hours, business hours, and sleep hours in most locations will still be tied roughly to sunrise/noon/sunset.
People are still going to want uniform event times within an area--almost no one wants businesses to open 50 seconds later in Seattle than in Redmond, for example.
We will still end up with strips separated by longitude boundaries, with events synchronized within each strip. We'll probably still synchronize each strip so that events are one hour or one half hour later than the strip to their east.
To answer questions like "is it too late to call my friend in <X> now?" where X is someplace outside your strip, you need the offset of your strip from UTC and the offset of your friend's strip. From the difference of those, and the UTC time of normal bed time in your strip, you can figure out if it is probably past bedtime in your friend's strip.
These "strips" are pretty much the same as our current "time zones".

The earth being roughly spherical does not mean time zones are needed. Why would it?

My immediate thought whenever I encounter the no time zone crowd is what units of time do you think make sense?
Once we throw our time zones the concept of a day no longer seems very useful — each season works out to about 2 kilohours or 8 megaseconds.
What is there to gain from messing with units of time?
