-Data Formatter
+数据格式器
 ==============
 
+Yii提供一个格式化类来格式化输出，以使输出数据对终端用户更友好易读，
+[[yii\i18n\Formatter]] 是一个助手类，作为 [应用组件](structure-application-components.md) 使用，默认名为`formatter`。
 For formatting of outputs Yii provides a formatter class to make data more readable for users.
 [[yii\i18n\Formatter]] is a helper class that is registered as an [application component](structure-application-components.md) named `formatter` by default.
 
+它提供一些方法用来格式化数据，如日期/时间、数字或其他常用的本地化格式，
+两种方式使用格式器：
 It provides a set of methods for data formatting purpose such as date/time values, numbers and other commonly used formats in a localized way.
 The formatter can be used in two different ways.
 
+1. 直接使用格式化方法(所有的格式器方法以 `as`做前缀):
 1. Using the formatting methods (all formatter methods prefixed with `as`) directly:
 
    ```php
-   echo Yii::$app->formatter->asDate('2014-01-01', 'long'); // output: January 1, 2014
-   echo Yii::$app->formatter->asPercent(0.125, 2); // output: 12.50%
-   echo Yii::$app->formatter->asEmail('cebe@example.com'); // output: <a href="mailto:cebe@example.com">cebe@example.com</a>
-   echo Yii::$app->formatter->asBoolean(true); // output: Yes
-   // it also handles display of null values:
-   echo Yii::$app->formatter->asDate(null); // output: (Not set)
+   echo Yii::$app->formatter->asDate('2014-01-01', 'long'); // 输出: January 1, 2014
+   echo Yii::$app->formatter->asPercent(0.125, 2); // 输出: 12.50%
+   echo Yii::$app->formatter->asEmail('cebe@example.com'); // 输出: <a href="mailto:cebe@example.com">cebe@example.com</a>
+   echo Yii::$app->formatter->asBoolean(true); // 输出: Yes
+   // 也可处理null值的输出显示:
+   echo Yii::$app->formatter->asDate(null); // 输出: (Not set)
    ```
 
-2. Using the [[yii\i18n\Formatter::format()|format()]] method and the format name.
-   This method is also used by widgets like [[yii\grid\GridView]] and [[yii\widgets\DetailView]] where you can specify
-   the data format of a column in the widget configuration.
+2. 使用 [[yii\i18n\Formatter::format()|format()]] 方法和格式化名，
+   该方法也被一些小部件如[[yii\grid\GridView]] 和 [[yii\widgets\DetailView]]使用，在小部件配置中可以指定列的数据格式。
 
    ```php
-   echo Yii::$app->formatter->format('2014-01-01', 'date'); // output: January 1, 2014
-   // you can also use an array to specify parameters for the format method:
-   // `2` is the value for the $decimals parameter of the asPercent()-method.
-   echo Yii::$app->formatter->format(0.125, ['percent', 2]); // output: 12.50%
+   echo Yii::$app->formatter->format('2014-01-01', 'date'); // 输出: January 1, 2014
+   // 可使用数组来指定格式化方法的参数：
+   // `2` 是asPercent()方法的参数$decimals的值
+   echo Yii::$app->formatter->format(0.125, ['percent', 2]); // 输出: 12.50%
    ```
 
+当[PHP intl extension](http://php.net/manual/en/book.intl.php)安装时，格式器的输出会本地化，
+为此可配置格式器的 [[yii\i18n\Formatter::locale|locale]] 属性，如果没有配置，
+应用配置 [[yii\base\Application::language|language]] 作为当前区域，更多详情参考 [国际化](tutorial-i18n.md)一节。
+然后格式器根据当前区域为日期和数字选择正确的格式，包括月份和星期也会转换到当前语言，
+日期格式也会被 [[yii\i18n\Formatter::timeZone|timeZone]] 参数影响，
+该参数如果没有明确配置会使用应用的 [[yii\base\Application::timeZone|from the application]] 参数。
 All output of the formatter is localized when the [PHP intl extension](http://php.net/manual/en/book.intl.php) is installed.
 You can configure the [[yii\i18n\Formatter::locale|locale]] property of the formatter for this. If not configured, the
 application [[yii\base\Application::language|language]] is used as the locale. See the [section on internationalization](tutorial-i18n.md) for more details.

 week days translated to the current language. Date formats are also affected by the [[yii\i18n\Formatter::timeZone|timeZone]]
 which will also be taken [[yii\base\Application::timeZone|from the application]] if not configured explicitly.
 
+日期格式根据不同区域输出不同的结果，如下例所示：
 For example the date format call will output different results for different locales:
 
 ```php
 Yii::$app->formatter->locale = 'en-US';
-echo Yii::$app->formatter->asDate('2014-01-01'); // output: January 1, 2014

 Formatting Date and Time values <a name="date-and-time"></a>
 -------------------------------
 
+格式器类为格式化日期和时间提供了多个方法：
 The formatter class provides different methods for formatting date and time values. These are:
 
+- [[yii\i18n\Formatter::asDate()|date]] - 值被格式化成日期，如 `January, 01 2014`.
+- [[yii\i18n\Formatter::asTime()|time]] - 值被格式化成时间，如 `14:23`.
+- [[yii\i18n\Formatter::asDatetime()|datetime]] - 值被格式化成日期和时间，如 `January, 01 2014 14:23`.
+- [[yii\i18n\Formatter::asTimestamp()|timestamp]] - 值被格式化成 [unix 时间戳](http://en.wikipedia.org/wiki/Unix_time) 如 `1412609982`.
+- [[yii\i18n\Formatter::asRelativeTime()|relativeTime]] - 值被格式化成和当前时间比较的时间间隔并用人们易读的格式，如`1 hour ago`.
 - [[yii\i18n\Formatter::asDate()|date]] - the value is formatted as a date e.g. `January, 01 2014`.
 - [[yii\i18n\Formatter::asTime()|time]] - the value is formatted as a time e.g. `14:23`.
 - [[yii\i18n\Formatter::asDatetime()|datetime]] - the value is formatted as date and time e.g. `January, 01 2014 14:23`.

 properties [[yii\i18n\Formatter::$dateFormat|$dateFormat]], [[yii\i18n\Formatter::$timeFormat|$timeFormat]], and
 [[yii\i18n\Formatter::$datetimeFormat|$datetimeFormat]].
 
+格式器默认会使用一个快捷格式，它根据当前启用的区域来解析，
+这样日期和时间会格式化成用户国家和语言通用的格式，
+有四种不同的快捷格式：
 By default the formatter uses a shortcut format that is interpreted differently according to the currently active locale
 so that dates and times are formatted in a way that is common for the users country and language.
 There are four different shortcut formats available:
 
-- `short` in `en_GB` locale will print for example `06/10/2014` for date and `15:58` for time, while
-- `medium` will print `6 Oct 2014` and `15:58:42`,
-- `long` will print `6 October 2014` and `15:58:42 GMT`,
-- and `full` will print `Monday, 6 October 2014` and `15:58:42 GMT`.
+- `en_GB`区域的 `short` 会打印日期为 `06/10/2014`，时间为 `15:58`
+- `medium` 会分别打印 `6 Oct 2014` 和 `15:58:42`,
+- `long` 会分别打印 `6 October 2014` 和 `15:58:42 GMT`,
+- `full` 会分别打印 `Monday, 6 October 2014` 和 `15:58:42 GMT`.
 
+另外你可使用[ICU 项目](http://site.icu-project.org/) 定义的语法来自定义格式，
+ICU项目在该URL：<http://userguide.icu-project.org/formatparse/datetime>下的手册有介绍，
+或者可使用PHP [date()](http://php.net/manual/de/function.date.php) 方法的语法字符串并加上前缀`php:`.
 Additionally you can specify custom formats using the syntax defined by the
 [ICU Project](http://site.icu-project.org/) which is described in the ICU manual under the following URL:
 <http://userguide.icu-project.org/formatparse/datetime>. Alternatively you can use the syntax that can be recognized by the
 PHP [date()](http://php.net/manual/de/function.date.php)-function using a string that is prefixed with `php:`.
 
 ```php
-// ICU format
+// ICU 格式化
 echo Yii::$app->formatter->asDate('now', 'yyyy-MM-dd'); // 2014-10-06
-// PHP date()-format
+// PHP date()-格式化
 echo Yii::$app->formatter->asDate('now', 'php:Y-m-d'); // 2014-10-06
 ```
 
+### 时区 <a name="time-zones"></a>
 ### Time zones <a name="time-zones"></a>
 
+当格式化日期和时间时，Yii会将它们转换为对应的 [[yii\i18n\Formatter::timeZone|configured time zone]] 时区，
+输入的值在没有指定时区时候会被当作UTC时间，因此，推荐存储所有的日期和时间为UTC而不是UNIX时间戳，UNIX通常也是UTC。
+如果输入值所在的时区不同于UTC，时区应明确指定，如下所示：
 When formatting date and time values, Yii will convert them to the [[yii\i18n\Formatter::timeZone|configured time zone]].
 Therefor the input value is assumed to be in UTC unless a time zone is explicitly given. For this reason
 it is recommended to store all date and time values in UTC preferably as a UNIX timestamp, which is always UTC by definition.
 If the input value is in a time zone different from UTC, the time zone has to be stated explicitly like in the following example:
 
 ```php
-// assuming Yii::$app->timeZone = 'Europe/Berlin';
+// 假定 Yii::$app->timeZone = 'Europe/Berlin';
 echo Yii::$app->formatter->asTime(1412599260); // 14:41:00
 echo Yii::$app->formatter->asTime('2014-10-06 12:41:00'); // 14:41:00
 echo Yii::$app->formatter->asTime('2014-10-06 14:41:00 CEST'); // 14:41:00
 ```

-  `null` values will be formatted using [[nullDisplay]].
-- [[yii\i18n\Formatter::asText()|text]] - the value is HTML-encoded.
-  This is the default format used by the [GridView DataColumn](output-data-widgets.md#data-column).
-- [[yii\i18n\Formatter::asNtext()|ntext]] - the value is formatted as an HTML-encoded plain text with newlines converted
-  into line breaks.
-- [[yii\i18n\Formatter::asParagraphs()|paragraphs]] - the value is formatted as HTML-encoded text paragraphs wrapped
-  into `<p>` tags.
-- [[yii\i18n\Formatter::asHtml()|html]] - the value is purified using [[HtmlPurifier]] to avoid XSS attacks. You can
-  pass additional options such as `['html', ['Attr.AllowedFrameTargets' => ['_blank']]]`.
-- [[yii\i18n\Formatter::asEmail()|email]] - the value is formatted as a `mailto`-link.
-- [[yii\i18n\Formatter::asImage()|image]] - the value is formatted as an image tag.
-- [[yii\i18n\Formatter::asUrl()|url]] - the value is formatted as a hyperlink.
-- [[yii\i18n\Formatter::asBoolean()|boolean]] - the value is formatted as a boolean. By default `true` is rendered
-  as `Yes` and `false` as `No`, translated to the application language. You adjust this by configuring
-  the [[yii\i18n\Formatter::booleanFormat]]-property.
