Package: tzdata Version: 2021a-1+deb11u10 Severity: important Tags: patch X-Debbugs-Cc: deb...@kayari.org
Dear Maintainer, * What led up to the situation? GCC 13 uses the /usr/share/zoneinfo/tzdata.zi file to implement support for the C++20 time zone library. * What exactly did you do (or not do) that was effective (or ineffective)? Basic use of std::chrono::tzdb with GCC 13 fails on Debian stable, because the tzdata.zi file cannot be parsed, and so only UTC time zones are supported. I originally filed this upstream: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109857 Further investigation revealed it's a Debian-specific bug in the tzdata.zi file. * What was the outcome of this action? Attempting to use any non-UTC time zone in C++ programs will fail. * What outcome did you expect instead? The tzdata.zi file should be valid according to the zic(8) man page. Specifically: The fields that make up a rule line are: [...] TO Gives the final year in which the rule applies. In addition to minimum and maximum (as above), the word only (or an abbreviation) may be used to repeat the value of the FROM field.
