Our user likes to be able to fine by the (5) minutes for hourly loans (2h, 4h, etc...). One solution would be to change (hack) the fine amount and grace and... to allow for fraction. An easier solution is simply to add "minutes" as a unit. Code change was very simple, but the Calendar and Holiday mechanisms have changed since, so I'll see how to do it all cute again. ALSO: One area of discussion with the user was about the meaning of a 24h loan. Unit=Hours, Period=24. If the library is opened only 10h per day, this is not a 3 day rental. This should be a "same time tomorrow, fines by the hour". Comments welcomed.
Created attachment 29337 [details] [review] Bug 11055 - Add 'Minutes' as a load period unit WARNING: This patch is dependent on http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8133. My patch on bug 8133 ensures proper calculation of overdues. Minutes are added as a unit in circulation rules. A test script is provided: 't/Circulation/minuteloan.t'.
