Bug #11071

Updated by nobu (Nobuyoshi Nakada) over 5 years ago

I have this Gemfile: 

 ```ruby ``` 
 source 'https://rubygems.org' 

 ruby '2.2.2' 

 gem 'rspec' 
 gem 'timecop' 
 ``` 

 producing this Gemfile.lock: 

 ``` 
 GEM 
   remote: https://rubygems.org/ 
   specs: 
     diff-lcs (1.2.5) 
     rspec (3.2.0) 
       rspec-core (~> 3.2.0) 
       rspec-expectations (~> 3.2.0) 
       rspec-mocks (~> 3.2.0) 
     rspec-core (3.2.3) 
       rspec-support (~> 3.2.0) 
     rspec-expectations (3.2.1) 
       diff-lcs (>= 1.2.0, < 2.0) 
       rspec-support (~> 3.2.0) 
     rspec-mocks (3.2.1) 
       diff-lcs (>= 1.2.0, < 2.0) 
       rspec-support (~> 3.2.0) 
     rspec-support (3.2.2) 
     timecop (0.7.3) 

 PLATFORMS 
   ruby 

 DEPENDENCIES 
   rspec 
   timecop 
 ``` 

 and this test file: 

 ```ruby ``` 
 # timecop_spec.rb 

 require 'timecop' 

 describe Timecop do 
   around do |example| 
     Timecop.travel(Time.parse('2015-01-01 06:30:00'), &example) 
   end 

   it 'sets the current time' do 
     Timecop.travel(Time.parse('2015-01-01 09:30:00')) {} 
   end 
 end 
 ``` 

 When I run `bundle exec rspec -c timecop_spec.rb`, this is the output: 

 ```
