</script>
```

## API

### format

> format time

```js
new Date('2015-10-12 23:01:11').format("yyyy年MM月dd日 hh:mm:ss");
//⇒ "2015年10月12日 23:01:11"

var testDate = new Date(); 
var testStr = testDate.format("yyyy年MM月dd日hh小时mm分ss秒"); 
//=> testStr =  2015年01月20日 19小时21分03秒
```

### ago

> How many hours ago, how many minutes ago, how many seconds ago

```js
new Date(1421313395359).ago(1411430400000)
//=> "3个月前"

new Date(1421313395359).ago('1987-04-03')
//=> "28年前"

new Date('2010-02-02').ago('1987-04-03')
//=> "23年前"
```

### toHHMMSS

> Time conversion, countdown 'milliseconds'.toHHMMSS(output format)
> This is an extension based on the String prototype

```js
var dt = (new Date().getTime()).toString()
dt.toHHMMSS('hh时mm分ss秒') //=> 34时11分52秒
```

### TZC

> Solve the inaccurate display of server time due to time zone changes

```js
// The server's incoming front-end is generally seconds, and the front-end timestamp is milliseconds, so it needs to be multiplied by 1000
// 8 is the server time time zone
new Date(1434701732*1000).TZC(8)
```
