Fri Jan 10 15:41:15 UTC 2020
gmtime_r/localtime_r are mostly used in combination with
strftime to format timestamps in libvirt. This can all

that is also more portable.
There is some boundary condition problem in parsing POSIX
timezone offsets in GLib which tickles our test suite.
The test suite is hacked to avoid the problem. The upsteam
GLib bug report is
