How to add minutes to a Time object
提问by keruilin
In Ruby, how do I do Time.now + 10.hours?
在 Ruby 中，我该怎么做Time.now + 10.hours？
Is there an equivalent for secsand mins? For example:
是否有一个等效secs和mins？例如：
Time.now + 15.mins
回答by Phrogz
Ruby (the programming language) doesn't have 10.hours, that's ActiveSupportas part of Ruby on Rails (the web framework). And yes, it does have both minutesand secondsmethods.
Ruby（编程语言）没有10.hours，它ActiveSupport是 Ruby on Rails（Web 框架）的一部分。是的，它确实有minutes和seconds方法。
However, Time#+(the + method on Time instances) returns a new Time instance that is that many seconds in the future. So without any Ruby on Rails sugar, you can simply do:
但是，Time#+（Time 实例上的 + 方法）返回一个新的 Time 实例，该实例是未来几秒钟的时间。因此，没有任何 Ruby on Rails 糖，您可以简单地执行以下操作：
irb> t = Time.now
#=> 2011-08-03 22:35:01 -0600
irb> t2 = t + 10 # 10 Seconds
#=> 2011-08-03 22:35:11 -0600
irb> t3 = t + 10*60 # 10 minutes
#=> 2011-08-03 22:45:01 -0600
irb> t4 = t + 10*60*60 # 10 hours
#=> 2011-08-04 08:35:01 -0600

If you are using ActiveSupport, what you are looking for is the full .minutesand .seconds.
如果您正在使用 ActiveSupport，那么您正在寻找的是完整的.minutes和.seconds.
Time.now + 10.minutes
Time.now + 10.seconds

Also in ActiveSupport you can do:
同样在 ActiveSupport 中，您可以执行以下操作：
10.minutes.from_now
10.minutes.ago

I think you're talking about extensions added by Rails. I think you need 15.minutes.
我认为您在谈论 Rails 添加的扩展。我认为你需要15.minutes.
See the Active Support Core Extensions for Date, DateTime and Timefor more information.
