gmtime_r/localtime_r are mostly used in combination with strftime to format timestamps in libvirt. This can all be replaced with GDateTime resulting in simpler code 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 https://gitlab.gnome.org/GNOME/glib/issues/1999 Reviewed-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
