(time1 - time2) / 60
(时间 1 - 时间 2) / 60
If the time objects are string, Time.parse(time)them first
如果时间对象是字符串，Time.parse(time)它们首先

If you subtract two Date or DateTime objects, the result is a Rational representing the number of days between them. What you need is:
如果将两个 Date 或 DateTime 对象相减，则结果是一个 Rational，表示它们之间的天数。你需要的是：
a = Date.new(2009, 10, 13) - Date.new(2009, 10, 11)
(a * 24 * 60).to_i # 2880 minutes
or
或者
a = DateTime.new(2009, 10, 13, 12, 0, 0) - DateTime.new(2009, 10, 11, 0, 0, 0)
(a * 24 * 60).to_i # 3600 minutes

start_time = Time.new(2013,1)
end_time = Time.new(2014,1)
TimeDifference.between(start_time, end_time).in_minutes

Let's say you have two dates task_signed_inand task_signed_outfor a simple @userobject. We could do like this:
假设您有两个日期task_signed_in和task_signed_out一个简单的@user对象。我们可以这样做：
(@user.task_signed_out.to_datetime - @user.task_signed_in.to_datetime).to_i
This will give you result in days. Multiply by 24you will get result in hours and again multiply by 60you will result in minutes and so on.
这将在几天内为您提供结果。乘以24您将得到数小时的结果，再次乘以您将得到60数分钟，依此类推。
This is the most up to date solution tested in ruby 2.3.x and above.
这是在 ruby 2.3.x 及更高版本中测试的最新解决方案。
