I think its a shame that :
1. the current handbook way to change timezone is manually editing a file.
2. the handbook doesn't mention `eselect locale`
3. `eselect locale list` is useless if you have *all* locales available to you.
4. `eselect locale` can only set the LANG variable.
5. that eselect doesn't have an interactive mode yet.
Why? because this problem could be made simpler by providing a way to
use a recommended locale for your timezone, which is likely to yield a
more sane default for that timezone.
It would also make it easier to validate the value the user chooses
for their Timezone value.
Consider:
eselect timezone list
# all level 1 timezones + groups , ie: like ls /usr/share/zoneinfo
eselect timezone list America/
# contents of /usr/share/zoneinfo/America
eselect timezone set America/Chicago
# /etc/timezone is updated to 'America/Chicago'
# /etc/localtime is replaced with /usr/share/zoneinfo/America/Chicago
eselect locale set --all auto
# LANG and LC_* are set using the values defined as "default" for
America/Chicago
eselect locale set --ctype auto
# Only LC_CTYPE is autopopulated.
eselect locale list
# 600 items because you have a vanilla locale.defs
eselect locale list --timezone
# shows a list of LOCALE values for the current TZ, with the one that
would be used as default first/marked up differently
eselect locale list en
# shows english locale options
eselect locale set --ctype en_US.utf8
The benefits of setting these locales this way are obvious to me at
least, you can set locales to a value that is sensible automatically.
You also can validate a users choice of locale and provide feedback,
such as, you can list non-installed locales, and then tell the user if
thy try to use a locale that isn't installed yet they need to update
locales.def
The only way I can suggest something better, would be an interactive
locale setter, something like 'tzselect' , except sets timezone *and*
locale information, with the ability to automatically update
locales.def and add new locale definitions and regenerate the locale
database.
This way, you could have a selection process more like this:

#? 1
The following information has been given:
United States
Eastern Time
Therefore TZ='America/New_York' will be used.
Local time is now: Thu Aug 2 17:33:17 EDT 2012.
Universal Time is now: Thu Aug 2 21:33:17 UTC 2012.
Is the above information OK?
1) Yes
2) No
#? 1
Your Current locale settings are:
LANG="POSIX"
The recommended settings for your locale are :
LANG="en_US.utf8"
LC_CTYPE="en_US.utf8"
Do you wish to change your locale settings at this time?
1) No
2) Yes - Use recommended settings
3) Yes - Configure locale interactively.
At least this way, the effort required to configure your system into a
very good logical UTF8 default is trivial.
