The problem is: People don't use UTC. They use local time. And there is 
no chance to convert local time to UTC without introducing errors.

See e.g. this page for some information about timezone irregularities: 
<http://webexhibits.org/daylightsaving/f.html>

If I'm forced to use UTC to store an event in Chandler and lawmakers 
change daylight time, I might come one hour too early or too late to my 
appointment.

Maybe you want to store birth dates in Chandler, including the exact 
time? And not just of living persons, but also of your grandparents? Do 
you always know the correct timezone? How do you convert these dates to UTC?

These are border cases. But I think Chandler should be able to handle 
border cases, not just the usual cases where timezone conversion works.
