ruby-on-rails - 在 DateTime 减法中返回分钟

Question

以下返回 (5/12)，一个 Rational 对象。

d = DateTime.current
d2 = d + 10.hours
d2 - d

我如何得到两个时间点的分钟差？

Answer 1

(d2 - d).class
=> Rational

Rational: A rational number can be represented as a paired integer number; a/b (b>0). Where a is numerator and b is denominator. Integer a equals rational a/1 mathematically.

d2 - d
=> (5/12)  #get the number of days

((d2 - d) * 24 * 60).to_i
=> 600    # get the number of minutes
