Ruby strftime：没有前导零的月份？ [英] Ruby strftime: Month without leading zero?

问题描述

Ruby的 strftime 有没有前导零的月份的格式？

Does Ruby's strftime have a format for the month without a leading zero?

我发现％e 获得一天没有领先的零，但没有运气与这个月。

I found %e for getting the day without the leading zero, but not having any luck with the month.

最终想要一个日期格式化喜欢： 9/1/2010

Ultimately wanting a date formatted like: 9/1/2010

推荐答案

某些版本的 strftime 允许使用减去的前缀格式化前导零，例如：

Some versions of strftime do allow prefixing with minus to format out leading zeros, for eg:

strftime "%-d/%-m/%y"

这将取决于您的系统上的 strftime 。所以为了一致性，我会做这样的事情：

However this will depend on strftime on your system. So for consistency I would do something like this instead:

dt = Time.local(2010, 'Sep', 1)
printf "%d/%d/%d", dt.day, dt.month, dt.year
