http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=9041 --- Comment #1 from Humberto Blanco <hblancoca@gmail.com> --- Review the source code i found that in Koha::Calendar.pm, in the sub addDate when evaluate $self->is_holiday($dt) the results for $dt appears bad, then in the Circulation.pm returns INVALID_DATE and needs manually checkout. For my biblio, i assume that all loans not in holidays then i put this in Koha::Calendar.pm if ( $days_mode eq 'Datedue' ){ my $dt = $base_date + $add_duration; if($unit ne 'hours'){ # Added for me while ( $self->is_holiday($dt) ) { $dt->add_duration($day_dur); if ( $unit eq 'hours' ) { $dt->set_hour($return_by_hour); # Staffs specific } } } # End added for me return $dt; } -- You are receiving this mail because: You are the assignee for the bug.
