zic is the Zone Information Compiler from the 4.3 BSD Tahoe baseline.
Programs compiled with -systype bsd43 wind up using libraries that use
the compiled timezone information processed by zic.  This is more flexible
and elegant than the System V support of timezones.  There is a man page
for zic, and I believe there was some brief discussion of it in the
Release Notes.

As has been discussed here before, when you are unlucky enough not to
be in the US/Pacific timezone (the default), you must change both
the System V and BSD 4.3 notions of what timezone you're in.  The
System V one is set from the contents of the file /etc/TZ which is
"classic" system V, XXXNYYY
  where:
  XXX - three letter standard time abbreviation
  N   - offset from GMT
  YYY - three letter daylight savings time abbrev
The BSD 4.3 timezone is set using "zic -l ZONENAME"  where, unfortunately,
the ZONENAMES are not obvious to the casual user.  Look in /etc/zoneinfo/SOURCES
for their values.

I suppose that in a perfect world, we'd settle on one mechanism.  Fears of
hidden compatibility problems and the perennial resource crunch have not
yet allowed this to happen.  Work for another day!

I'd expect our Customer Support Hotline can fill in any missing details about
this if anybody is having trouble.  They're usually quite helpful.
