Ruby中的时间ISO 8601 [英] Time ISO 8601 in Ruby

问题描述

我正在尝试以这种格式返回日期

I am trying to return a date with this format

2015-10-07T00：32：50.877 + 0000

2015-10-07T00:32:50.877+0000

我已经测试过

 Time.now.iso8601
 => "2015-10-21T09:47:50-04:00"

但我没有相同格式

tks

推荐答案

您可以自己使用strftime并创建此处

You can use strftime yourself and create the format you want as described here

您指定的格式应为％Y-％m-％dT％H：％M：％S.％L％z

因此完整的Ruby语句将为 Time.now.strftime（'％Y-％m-％dT％H：％M：％S.％L％z'）

And so the complete Ruby statement would be Time.now.strftime('%Y-%m-%dT%H:%M:%S.%L%z')

各种ISO 8601格式：
