The timepicker is used to allow the user to enter a time. It contains three fields to enter the hour, minute and second. Arrow buttons next to the fields allow the values to be adjusted with the mouse. A fourth textbox appears for 12 hour clocks which allows selection of AM or PM.
To specify the initial, use the value attribute set to a value of either the form HH:MM:SS or HH:MM. The value may be retrieved and changed using the value property or the dateValue property. The former specifies the time as a string of the form HH:MM:SS whereas the latter specifies the time as a Date object. In addition, the hour, minute and second properties may be used to retrieve and modify each component of the time separately.
The change event is fired whenever the time is changed. However, as described in Mozilla bug #799219, a change event handler may encounter erratic behavior when the time is changed using the keyboard instead of the mouse. To avoid this, you can use the workaround described here, i.e., use window.setTimeout(actual-event-handler-function, 0); to queue up your event handler to run after the rest of the picker's change event handlers.

Attributes
disabled- Type: boolean
- Indicates whether the element is disabled or not. If this attribute is set, the element is disabled. Disabled elements are usually drawn with grayed-out text. If the element is disabled, it does not respond to user actions, it cannot be focused, and the
command event will not fire. In the case of form elements, it will not be submitted. Do not set the attribute to true, as this will suggest you can set it to false to enable the element again, which is not the case.
The disabled attribute is allowed only for form controls. Using it with an anchor tag (an <a> link) will have no effect.
The element will, however, still respond to mouse events. To enable the element, leave this attribute out entirely.
- Visible controls have a
disabled property which, except for menus and menuitems, is normally preferred to use of the attribute, as it may need to update additional state.
