/**
- * @class Ext.Date
- * A set of useful static methods to deal with date
- * Note that if Ext.Date is required and loaded, it will copy all methods / properties to
- * this object for convenience
+  
/**
+ * A date picker. This class is used by the Ext.form.field.Date field to allow browsing and selection of valid
+ * dates in a popup next to the field, but may also be used with other components.
  *
- * The date parsing and formatting syntax contains a subset of
- * <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
- * supported will provide results equivalent to their PHP versions.
+ * Typically you will need to implement a handler function to be notified when the user chooses a date from the picker;
+ * you can register the handler using the {@link #select} event, or by implementing the {@link #handler} method.
  *
- * The following is a list of all currently supported formats:

-    UniversalSortableDateTime: "Y-m-d H:i:sO",

-var dt = new Date();
-console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));
