add 15 minutes to timefield

Question

I use two timefields. One is the starttime and the other the endtime. When i select a time in the starttime i load this value into the endtime:

{
xtype: 'timefield',
flex: 1,
margins: '10',
maxHeight: 25,
maxWidth: 100,
fieldLabel: '',
labelAlign: 'top',
name: 'startTijd',
allowBlank: false,
altFormats: 'G:i',
format: 'G:i',
listeners: {
    change: {
        fn: me.onTimefieldChange,
        scope: me
    }
}

}

This is the function for the listener

onTimefieldChange: function (field, newValue, oldValue, eOpts) {
  Ext.getCmp('eindTijd').setValue(newValue);
}

But what i want is that when i select starttime = 14:00 the endtime will automaticly increase it with one step for the endtime in this case 14:15. I tried to add 15 to the newValue but that will add 15 to the GMT

Ext provides the Ext.Date.add for this kind of manipulations. With your code, that would be something like:

onTimefieldChange: function (field, newValue, oldValue, eOpts) {
    var convertedValue = Ext.isEmpty(newValue)
        ? null
        : Ext.Date.add(newValue, Ext.Date.MINUTE, 15);
    Ext.getCmp('eindTijd').setValue(convertedValue);
}

add 15 minutes to timefield
