效果图：

只需要时、分选项如下：

             xtype: 'timefield',
             picker: {
                 slotOrder: ['hour', 'minute']
             },
             dateFormat: 'H:i',
             value: new Date()

一些额外的css：

 /*#region pick */

 .x-picker-slot-title {
     height:auto;
     text-align:center;
     padding:0.2em 0;
 }
 .x-picker-slot .x-dataview-item {
     padding:0 8px !important;
 }
 .x-webkit .x-layout-box.x-horizontal > .x-layout-box-item.x-picker-slot {
     width:auto !important;
 }
 /*#endregion*/
