+      Querying the host operating system (if supported and allowed by the OS). This uses an algorithm
+      that has to <strong>guess</strong> the timezone. This is by no means going to work correctly for 
+      every situation. A warning is shown when this stage is reached. Do not rely on it to be guessed
+      correctly, and set <link linkend="ini.date.timezone">date.timezone</link> to the correct timezone
+      instead.
