Description of problem: While testing ausearch time parsing we recently discovered that some locales have broken date and time. In particular, a time given by strftime() cannot be parsed correctly by strptime() afterwards. In RHEL-6.8 Snapshot 2.0 there are 50 such locales, the list of them is attached to this BZ. A test case for glibc prepared by Steve Grubb is attached to this BZ as well. Version-Release number of selected component (if applicable): glibc-2.12-1.192.el6 How reproducible: 100% Steps to Reproduce: 1. Compile the test case into test binary. 2. execute it for each locale (for L in $(locale -a); do ./test $L; done) Actual results: 50 broken locales, from ar_AE to my_MM.utf8. Expected results: No broken locales. Additional info: I would like to thank Steve to pointing to the issue and sharing the test case.

Upstream 2.22 has less broken locales: Error converting time string to struct in gd_GB locale Error converting time string to struct in gd_GB.iso885915 locale Error converting time string to struct in gd_GB.utf8 locale Error converting time string to struct in lzh_TW locale Error converting time string to struct in lzh_TW.utf8 locale Error converting time string to struct in my_MM locale Error converting time string to struct in my_MM.utf8 locale Same with upstream master (using a chroot script): FAIL: Error converting time string to struct in gd_GB locale FAIL: Error converting time string to struct in gd_GB.iso885915 locale FAIL: Error converting time string to struct in gd_GB.utf8 locale FAIL: Error converting time string to struct in lzh_TW locale FAIL: Error converting time string to struct in lzh_TW.utf8 locale FAIL: Error converting time string to struct in my_MM locale FAIL: Error converting time string to struct in my_MM.utf8 locale This is going to have to go upstream first. Depending on the change the backport may not be suitable for RHEL6, but might be for RHEL7 (I'll clone to there next). I filed an upstream bug. https://sourceware.org/bugzilla/show_bug.cgi?id=19890

Red Hat Enterprise Linux 6 transitioned to the Production 3 Phase on May 10, 2017. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available. This issue does not qualify, but we will consider incorporating an upstream change into Red Hat Enterprise Linux 7 if it becomes available.
