</span> * Provides a time input field with a time dropdown and automatic time validation.
 *
 * This field recognizes and uses JavaScript Date objects as its main {@link #value} type (only the time portion of the
 * date is used; the month/day/year are ignored). In addition, it recognizes string values which are parsed according to
 * the {@link #format} and/or {@link #altFormats} configs. These may be reconfigured to use time formats appropriate for
 * the user's locale.
 *
 * The field may be limited to a certain range of times by using the {@link #minValue} and {@link #maxValue} configs,
 * and the interval between time options in the dropdown can be changed with the {@link #increment} config.
 *
 * Example usage:
 *
 *     @example
 *     Ext.create('Ext.form.Panel', {
 *         title: 'Time Card',
 *         width: 300,
 *         bodyPadding: 10,
 *         renderTo: Ext.getBody(),
 *         items: [{
 *             xtype: 'timefield',
