tzselect — select a timezone
tzselect
The tzselect
      program asks the user for information about the current
      location, and outputs the resulting timezone description to
      standard output. The output is suitable as a value for the
      TZ environment variable.
All interaction with the user is done via standard input and standard error.
The exit status is zero if a timezone was successfully obtained from the user, nonzero otherwise.
AWKName of a Posix-compliant awk program (default: awk).
TZDIRName of the directory containing timezone data files
            (default: /usr/share/zoneinfo).
