Date formatting is broken (4.1.1)

[rliota]

Ext version tested:

• Ext 4.1.1

Browser versions tested against:

• Chrome

Description:
ExtJS's date formatter appears to be broken: 'time', 'timestamp', and 'u' all return invalid values. ('time' and 'timestamp' produce an - incomprehensible - alphanumeric string, and 'u' seems to produce "000" reliably.

Steps to reproduce the problem:

• Get a submit value from a datefield with submitFormat specified. (datefield.getSubmitValue())

The result that was expected:
A valid time, timestamp, or millisecond representation of the date.

The result that occurs instead:
An invalid time, timestamp, or millisecond representation of the date.

Test Case:

    Ext.onReady(function(){        
        timeStampDateField = Ext.create('Ext.form.field.Date',{
            fieldLabel:'\"timestamp\" formatter is broken',
            labelAlign:'right',
            renderTo:Ext.getBody(),
            labelWidth:150,
            margin:'0 0 10 0',
            submitFormat:'timestamp',
            listeners:{
                change:function(me){
                    alert("timestamp: "+me.getSubmitValue())
                }
            },
            minValue:new Date()
        });
        
        
        timeDateField = Ext.create('Ext.form.field.Date',{
            fieldLabel:'and so is \"time\"',
            labelAlign:'right',
            renderTo:Ext.getBody(),
            labelWidth:150,
            margin:'0 0 10 0',
            submitFormat:'time',
            listeners:{
                change:function(me){
                    alert("time: "+me.getSubmitValue())
                }
            },
            minValue:new Date()
        });
        
        timeDateField = Ext.create('Ext.form.field.Date',{
            fieldLabel:'and \"u\"',
            labelAlign:'right',
            renderTo:Ext.getBody(),
            labelWidth:150,
            margin:'0 0 10 0',
            submitFormat:'u',
            listeners:{
                change:function(me){
                    alert("u: "+me.getSubmitValue())
                }
            },
            minValue:new Date()
        });
        
    });
