A resolution on this issue was identified with Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001774
The behavior noted here is expected and correct. This is related to a bug/change in glibc 2.29. The failure can arise if timezone is not set (e.g., "Etc/UTC"), and possibly other scenarios that would result in tm_isdst < 0. The behavior of mktime differs on ubuntu 20.04 and 18.04 as they use different glibc versions. Aurelien with Debian notes this may be a bug for 18.04. Please see the thread with Debian for further detail. ** Bug watch added: Debian Bug tracker #1001774 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1001774 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954963 Title: tm_isdst=1 with mktime on 20.04 produces unexpected output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1954963/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
