+Subject: [PATCH] gdatetime test: Fall back if legacy System V PST8PDT is not
+ available
+
+On recent versions of Debian, PST8PDT is part of the tzdata-legacy
+package, which is not always installed and might disappear in future.
+Successfully tested with and without tzdata-legacy on Debian unstable.
+
+Upstream-Status: Backport [https://github.com/GNOME/glib/commit/fe2699369f79981dcf913af4cfd98b342b84a9c1]
