    /**
     * 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',
