https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=39748 Bug ID: 39748 Summary: Daylight savings breaks circulation Change sponsored?: --- Product: Koha Version: Main Hardware: All OS: All Status: NEW Severity: major Priority: P5 - low Component: Circulation Assignee: koha-bugs@lists.koha-community.org Reporter: katrin.fischer@bsz-bw.de QA Contact: testopia@bugs.koha-community.org CC: gmcharlt@gmail.com, kyle.m.hall@gmail.com This is an odd one, but it's happening in multiple instances in the same timezone: The timezone is Africa/Cairo. They switch to daylight savings on April 25, today. This makes 2025-04-25 00:00-00:59 invalid times. It's not possible to access any patron account's details or checkouts tab. They all result in an error 500. This means that circulation is no longer possible. In the logs there is only an error from plack-error.log: Invalid local time for date in time zone: Africa/Cairo. All other tabs in the patron account work, so we think it might have something to do with some of the code shared between circulation.pl and moremember.pl. As it appears in multiple instances it doesn't appear to be data related. It could be that today's date is generated in a wrong way and used for a comparison somewhere (see bug 32232 for a similar case)? -- You are receiving this mail because: You are watching all bug changes.
