Because Ruby is a server-side language and not a client-side language like JavaScript, Ruby uses the system clock from your web app server - and uses this information to calculate the time. Whatever timezone you have your system set to is what your Ruby app will use.从字符串中解析日期时, DateTime 将根据输入的格式进行最佳猜测:When parsing a date from a string, DateTime will make its best guess based on how the input is formatted:DateTime.parse('01/03')#=> Thu, 03 Jan 2019 00:00:00 +0000DateTime.parse('2019/01/03')#=> Thu, 03 Jan 2019 00:00:00 +0000DateTime.parse('01/03/2019')#=> Fri, 01 Mar 2019 00:00:00 +0000您也可以明确地 tell DateTime 如何使用 strptime 解析字符串:You can also explicitly tell DateTime how you want your string parsed using strptime:date = '01-03-2019'DateTime.strptime(date, '%m-%d-%Y')#=> Thu, 03 Jan 2019 00:00:00 +0000DateTime.strptime(date, '%d-%m-%Y')#=> Fri, 01 Mar 2019 00:00:00 +0000 这篇关于Ruby中的DateTime.parse()是否依赖于语言环境?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 07-23 00:09
