Most of Koha depends on the local timezone of the server, except for Koha::Database which support an ENV override with the key TZ.
We should take this a step further. We should not only accept the TZ environment variable for all of Koha, we should really be able to set the timezone in the koha conf file as well so we don't have to pass that environment variable to things like cronjobs and one-off scripts.
Test Plan:
1) Apply this patch
2) Set a timzone in your koha_conf file, that is *not* your local time zone
Available timzones are listed here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
3) Restart apache/plack
4) Perform some actions, check the timestamps in the database and in the
html output, note they are for the set timezone and not the local
timezone.
