Unix and linux systems have a timezone database that has the historic time
zones for everywhere they know about.  The internal time format is always
seconds since the beginning of 1970 UTC, and the libraries use the database
to convert back and forth to display formats.

Updating the timezone database is just like updating any other files in
your computer.  If you install the usual system updates, you'll be fine.
