horde time off Posted on October 14, 2014October 14, 2014 by ppadmin Horde was not reading the default server time (all users were seeing UTC). I set the default in this config file: /usr/share/psa-horde/imp/config/prefs.local.php I added this line: $_prefs[‘timezone’][‘value’] = ‘US/Central’; Posted in email, plesk and tagged horde, webmail.
