//Instead of having every field include a parameter include it in the prototype eg. altFormats: 'n/j/Y|m-d-Y|n-j-Y|n/j/y|m-d-y|n-j-y',

Ext.form.DateField.prototype.altFormats += '|n/d/Y g:i:s A|m/d/Y g:i:s A|n/j/Y g:i:s A|n-j-Y|n-j-y'; // makes dates like 7/27/1944 1:00:00 AM, 07/27/1944 1:00:00 AM, 7/7/1944 1:00:00 AM readable
