/**
* 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',
* name: 'in',
* fieldLabel: 'Time In',
* minValue: '6:00 AM',
* maxValue: '8:00 PM',
* increment: 30,
* anchor: '100%'
* }, {
* xtype: 'timefield',
* name: 'out',
* fieldLabel: 'Time Out',
* minValue: '6:00 AM',
* maxValue: '8:00 PM',
* increment: 30,
* anchor: '100%'
* }]
* });
