如何從Time.now獲取時區縮寫？

Time.now.strftime（'％Z'）爲我返回'Mountain Daylight Time'。我想獲得MDT。如何從Time.now獲取時區縮寫？

什麼是獲取時區縮寫的正確方法？

萬一有人懷疑我是誤導他們：

irb(main):001:0> Time.now.strftime('%Z') 
=> "Mountain Daylight Time" 
irb(main):002:0> Time.now.zone 
=> "Mountain Daylight Time" 
irb(main):003:0> Time.now.in_time_zone('Mountain Time (US & Canada)').zone 
=> "MDT"

真的嗎？當使用'Time.now.strftime（'％Z'）'時，我得到'CEST' - 即縮寫和[docs]（http://www.ruby-doc.org/core-2.0.0/Time .html＃method-i-strftime）說： '％Z - 簡稱時區名稱或類似信息。「＃ – dax

跑了幾件事情，我會說嘗試使用Time.now.zone

#This is working for me, but not for you. I'm not sure why (although others might!) 
$ > Time.now.strftime('%Z') 
=> "CEST" 

#This gives UTC time which is useful, but not what you're after 
$ > Time.zone 
=> #<ActiveSupport::TimeZone:0x00000103049918 @name="UTC", @utc_offset=nil, @tzinfo=#<TZInfo::TimezoneProxy: Etc/UTC>, @current_period=nil> 
$ > Time.zone.now 
=> Sat, 05 Oct 2013 09:11:01 UTC +00:00 
$ > Time.zone.now.zone 
=> "UTC" 

#This will (perhaps) return what you want. 
#It's possible that you'll still just get "Mountain Daylight Time" 
$ > Time.now 
=> 2013-10-05 11:12:09 +0200 
$ > Time.now.zone 
=> "CEST"
