Ruby:将日期和时间对象组合成一个日期时间 [英] Ruby: combine Date and Time objects into a DateTime

问题描述

简单的问题，但我找不到好的或明确的答案.将 Ruby 日期和时间对象(对象，而不是字符串)组合成单个 DateTime 对象的最佳和最有效的方法是什么?

Simple question, but I can't find a good or definitive answer. What is the best and most efficient way to combine Ruby Date and Time objects (objects, not strings) into a single DateTime object?

推荐答案

我发现了这个，但它没有你希望的那么优雅:

I found this, but it's not as elegant you would hope:

d = Date.new(2012, 8, 29)
t = Time.now
dt = DateTime.new(d.year, d.month, d.day, t.hour, t.min, t.sec, t.zone)

顺便说一下，ruby Time 对象还存储了年、月和日，因此您在创建 DateTime 时会将其丢弃.

By the way, the ruby Time object also stores a year, month, and day, so you would be throwing that away when you create the DateTime.
