在反映你的时区时，你可以使用这个

新日期() 新日期( 时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制。时间限制 ); var curr_time = dateString.toISOString()。代表(“T”，“”)。substr (0, 19); 游戏机。log (curr_time);

如果你使用Node.js，你肯定有EcmaScript 5，所以Date有一个toISOString方法。您要求对ISO8601进行轻微修改:

new Date().toISOString()
> '2012-11-04T14:51:06.157Z'

所以只要剪掉一些东西，你就搞定了:

new Date().toISOString().
  replace(/T/, ' ').      // replace T with a space
  replace(/\..+/, '')     // delete the dot and everything after
> '2012-11-04 14:55:45'

或者，在一行中:new Date(). toisostring()。replace(/T/， ' ').replace(/\..+ /”)

ISO8601必然是UTC(也由第一个结果的末尾Z表示)，因此默认情况下得到UTC(总是一件好事)。

我需要一个简单的格式化库，不需要locale和语言支持。所以我修改了

http://www.mattkruse.com/javascript/date/date.js

并且使用它。参见https://github.com/adgang/atom-time/blob/master/lib/dateformat.js

文档非常清楚。

new Date().toString("yyyyMMddHHmmss").
      replace(/T/, ' ').  
      replace(/\..+/, '') 

使用.toString()，这将变成格式 replace(/T/， ' ')。//替换T到' ' 2017-01-15T… 替换(/ . .+/， ") //for…13:50:16.1271

示例:参见var date and hour:

var日期”=“2017-01-15T13:50:16 1271。”“yyyyMMddHHmmss”toString()。 代表(/T/， ')。 replace(/)。+ / -); var auxCopia =日期。斯普利特(“”); 鉴于= auxCopia [0]; var时光= auxCopia [1]; 游戏机。log(日期); 游戏机。log(时光”);

UPDATE 2021-10-06: Added Day.js and remove spurious edit by @ashleedawg UPDATE 2021-04-07: Luxon added by @Tampa. UPDATE 2021-02-28: It should now be noted that Moment.js is no longer being actively developed. It won't disappear in a hurry because it is embedded in so many other things. The website has some recommendations for alternatives and an explanation of why. UPDATE 2017-03-29: Added date-fns, some notes on Moment and Datejs UPDATE 2016-09-14: Added SugarJS which seems to have some excellent date/time functions.

好吧，既然还没有人给出真正的答案，那我的答案就是。

库当然是以标准方式处理日期和时间的最佳选择。在日期/时间计算中有许多边缘情况，因此能够将开发移交给库是非常有用的。

以下是主要Node兼容的时间格式化库列表:

Day.js [added 2021-10-06] "Fast 2kB alternative to Moment.js with the same modern API" Luxon [added 2017-03-29, thanks to Tampa] "A powerful, modern, and friendly wrapper for JavaScript dates and times." - MomentJS rebuilt from the ground up with immutable types, chaining and much more. Moment.js [thanks to Mustafa] "A lightweight (4.3k) javascript date library for parsing, manipulating, and formatting dates" - Includes internationalization, calculations and relative date formats - Update 2017-03-29: Not quite so light-weight any more but still the most comprehensive solution, especially if you need timezone support. - Update 2021-02-28: No longer in active development. date-fns [added 2017-03-29, thanks to Fractalf] Small, fast, works with standard JS date objects. Great alternative to Moment if you don't need timezone support. SugarJS - A general helper library adding much needed features to JavaScripts built-in object types. Includes some excellent looking date/time capabilities. strftime - Just what it says, nice and simple dateutil - This is the one I used to use before MomentJS node-formatdate TimeTraveller - "Time Traveller provides a set of utility methods to deal with dates. From adding and subtracting, to formatting. Time Traveller only extends date objects that it creates, without polluting the global namespace." Tempus [thanks to Dan D] - UPDATE: this can also be used with Node and deployed with npm, see the docs

还有一些非node库:

Datejs[感谢Peter Olson] -没有打包在npm或GitHub中，所以不太容易与Node一起使用-不太推荐，因为自2007年以来没有更新!

你可以使用轻量级库Moment js

npm install moment

给图书馆打电话

var moments = require("moment");

现在转换成你需要的格式

moment().format('MMMM Do YYYY, h:mm:ss a');

更多格式和细节，你可以关注官方文档Moment js
