/**
* A time picker which provides a list of times from which to choose. This is used by the Ext.form.field.Time
* class to allow browsing and selection of valid times, but could also be used with other components.
*
* By default, all times starting at midnight and incrementing every 15 minutes will be presented. This list of
* available times can be controlled using the {@link #minValue}, {@link #maxValue}, and {@link #increment}
* configuration properties. The format of the times presented in the list can be customized with the {@link #format}
* config.
*
* To handle when the user selects a time from the list, you can subscribe to the {@link #selectionchange} event.
*
* @example
* Ext.create('Ext.picker.Time', {
* width: 60,
* minValue: Ext.Date.parse('04:30:00 AM', 'h:i:s A'),
* maxValue: Ext.Date.parse('08:00:00 AM', 'h:i:s A'),
* renderTo: Ext.getBody()
