On my system, zdump when prompted with America/Chicago says
"America/Chicago  Mon Aug 12 16:57:29 2019 CDT", which is useful
information.  I'm not in Chicago, but I specified it during
installation (actually I think my IP address allowed at least one
installer to correctly guess it), because it's the big city
"everyone" in the northern half of the US knows is in US Central
Time.  "CDT" because we're in Daylight Savings time right now.

So it would appear to be a seed to pick out which time zone you're
in from the timezone data file.  But this messiness I leave to the
experts, I only use timezone data progamatically.
