    This class behaves the same as <classname>DateTimeImmutable</classname>,
    except objects are modified itself when modification methods such as
    <function>DateTime::modify</function> are called.

   <warning>
    <para>
     Calling methods on objects of the class <classname>DateTime</classname>
     will change the information encapsulated in these objects, if you want to
     prevent that you will have to use <literal>clone</literal> operator to
     create a new object. Use <classname>DateTimeImmutable</classname>
     instead of <classname>DateTime</classname> to obtain this recommended
     behaviour by default.
