From Koha/Calendar.pm: if ( $unit eq 'hours' ) { # Fixed for legacy support. Should be set as a branch parameter my $return_by_hour = 10; $dt = $self->addHours($startdate, $add_duration, $return_by_hour);
Still valid.
Lack of properly working hourly loans functionality in Koha is a major problem for us. To prevent items being due back on weekends, all of our 8 libraries have every weekend day set to be closed days even though the libaries are open, and loaning hundreds of 5 hourly loans daily (mainly laptops). A fix to this bug would help reduce patron confusion with loan periods. But fully working hourly loans needs other fixes including those discussed in bug 6796 and bug 9725. And I suspect others.
