+Subject: [PATCH] clock-time: make change of system's timezone change time for
+ DEFAULT_TIMEZONE
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+clock_time->timezone is set in clock_time_init so the condition
+
+'clock_time->timezone != NULL
+
+is matching always.
+
+Tested by selecting seconds displayed (-> quick update) and changing timezone.
