Thanks for the hint. It looks rather difficult; cf tzfile(5), zic(8).

Moreover the system seems to be aware of CEST:

# date
dilluns,  7 de maig de 2007, 21:03:53 CEST
# zdump CEST
CEST  Mon May  7 19:04:03 2007 UTC
#

Looks to me rather as a problem with the way find parses dates. FWIW, my
login.conf reads:

[... my (indirect) login class:]
#
# Usuaris de La Franja. Català, UTF-8 i retocs
#
lafranja|usuaris de La Franja:\
        :lang=ca_ES.UTF-8:\
        :lc_all=ca_ES.UTF-8:\
        :lc_collate=ca_ES.UTF-8:\
        :lc_ctype=ca_ES.UTF-8:\
        :lc_messages=ca_ES.UTF-8:\
        :lc_monetary=ca_ES.UTF-8:\
        :lc_numeric=ca_ES.UTF-8:\
        :lc_time=ca_ES.UTF-8:\
        :charset=UTF-8:\
        :tc=default:
[...]

...but only LANG is passed to the environment -- i.e. LC_TIME is not:

# echo $LANG
ca_ES.UTF-8
# echo $LC_TIME
LC_TIME: Undefined variable.

I used to use the output of uname -v (words 5 to 9) with find in a q&d
script to backup custom config files, and this is worked around by now. Just
wonder if it deserves a PR.
