+/**
+ * <p>Seam component that provides a list of time zones, limited to time zones
+ * with IDs in the form Continent/Place, excluding deprecated three-letter time
+ * zone IDs. The time zones returned have a fixed offset from UTC, which takes
+ * daylight savings time into account. For example, Europe/Amsterdam is UTC+1;
+ * in winter this is GMT+1 and in summer GMT+2.</p>
+ *
+ * <p>The time zone objects returned are wrapped in an implementation of
+ * TimeZone that provides a more friendly interface for accessing the time zone
+ * information. In particular, this type provides a more bean-friend property
+ * for the time zone id (id than ID) and provides a convenience property named
+ * label that formats the time zone for display in the UI. This wrapper can be
+ * disabled by setting the component property wrap to false.</p>
