In my case: $ md5sum /usr/share/zoneinfo/Europe/Belgrade 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Belgrade $ md5sum /usr/share/zoneinfo/Europe/Sarajevo 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Sarajevo $ md5sum /usr/share/zoneinfo/Europe/* | grep 226ad0c2724b4674d6a9206a43661ff9 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Belgrade 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Ljubljana 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Podgorica 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Sarajevo 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Skopje 226ad0c2724b4674d6a9206a43661ff9 /usr/share/zoneinfo/Europe/Zagreb -- time-admin shows different time zone when it is restarted https://bugs.launchpad.net/bugs/43644 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
