[Koha] Errors in log, please help

Hi all after checking the log I found the following: [error] ERROR: Date::Manip unable to determine TimeZone., referer: http://my.site:8080/cgi-bin/koha/members/memberentry.pl?actionType=Add [error] [client 127.0.0.1] at /usr/lib/perl5/vendor_perl/5.8.5/Date/Manip.pm line 3495, referer: http://my.site:8080/cgi-bin/koha/members/memberentry.pl?actionType=Add All this while adding a new member, may be the first error is not that important, but don't know really. I'm working in the same machine as instalation as u can notice, also found that the httpuser was 'apache' and not the root or the koha user, does this really matter?
