I'm all for running servers in UTC, but most folks do seem to prefer to 
display the time values in their local timezone.

Because apps expect to be able to get and display time.

Because apps are increasingly being used by folks across timezones.

Because operating systems are assumed to be capable of maintaining 
something approximating the local time.

Because the operating system vendors variously can't get this timezone 
stuff right, and the end-users can have yet larger difficulties.

Because operating systems including OpenVMS use this data to manage the 
DST switch-over.

Any of the NT-based systems including Microsoft Windows XP and later 
all use the IANA (Olson) timezone data.  As do many (most?) other 
platforms.

OpenVMS and Windows do both have related issues here, as both share 
what I consider a design flaw; of maintaining the system clock in local 
and not in UTC.

Operating systems and related expectations are increasing in scale and 
scope, and have been for many years.  But an expectation of "proper" 
timekeeping support is a pretty old requirement.
