[Bug libstdc++/108409] std::chrono::current_zone() doesn't work on AIX or Windows
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108409 Mike Crowe changed: What|Removed |Added CC||mac at mcrowe dot com --- Comment #7 from Mike Crowe --- ICU tries to solve this problem with a table at https://github.com/unicode-org/icu/blob/fa6a4661ba002c1c1ee68cbf5c7ac9af75132d07/icu4c/source/common/putil.cpp#L802 and other heuristics in the same file. Based on my understanding, the table is incorrect for the Australian zones and US/Aleutian (it gets the short names wrong) and it's missing the non-DST US zones. I'm not sure if it's worth going to these lengths to try to map POSIX time zone strings to Olson names, but I thought I'd provide the link in case it's useful.
[Bug libstdc++/58931] condition_variable::wait_until overflowed by large time_point
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58931 Mike Crowe changed: What|Removed |Added CC||mac at mcrowe dot com --- Comment #6 from Mike Crowe --- This problem isn't as serious now that waiting on std::chrono::steady_clock doesn't use the generic wait_until implemenation, but it's worth fixing regardless. I have a reproduction case and Aaron's fix in attachment 43261 (with some minor tweaks to accommodate the recent addition of __detail::ceil) still appears to work.
[Bug libstdc++/93542] std::future::wait_for should use monotonic clock
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93542 Mike Crowe changed: What|Removed |Added Resolution|--- |FIXED Status|ASSIGNED|RESOLVED --- Comment #3 from Mike Crowe --- The patches mentioned in comment 2 landed for GCC 11 as 87fce1923fcc8d6ef508500475c149082dc9d338 and 01d412ef36f56c6961858f4d3d395d000e3f1c06 respectively. It seems that I failed to include the bug number in the commit message. :(

[Bug libstdc++/91486] future::wait_for and shared_timed_mutex::wait_for do not work properly with float duration
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91486 --- Comment #10 from Mike Crowe --- Unfortunately https://gcc.gnu.org/g:f9ddb696a289cc48d24d3d23c0b324cb88de9573 mentioned in comment 9 contains a small bug (all my fault) that Jonathan pointed out in https://gcc.gnu.org/pipermail/libstdc++/2020-September/051004.html . I've posted a fix in https://gcc.gnu.org/pipermail/libstdc++/2020-September/051025.html and I'll attach the patch here too.
