Use the following code to create a basic inputEx TimeField.
field = new Y.inputEx.TimeField({
parentEl: 'container1',
value:'15:17:34'
});
var button = inputEx.cn('button', null, null, 'getValue');
Y.one(button).on('click',function() {
alert(field.getValue());
});
Y.one('#container1').appendChild(button);
Use the separators attribute from CombineField to change the separator strings.
new Y.inputEx.TimeField({
parentEl: 'container2',
separators: [false,"h","m","s"],
value:'15:17:34'
});
