El método <methodname>DateInterval::format</methodname> no
|
|
recalcula los excesos en cadenas de hora ni en segmentos de fecha. Esto
|
|
es así porque no es posible analizar valores como <literal>"32 días"</literal>
|
|
el cual podría ser interpretado como cualquier cosa desde <literal>"1 mes y 4 días"</literal>
|
|
hasta <literal>"1 mes y un día"</literal>.
