how to find the time taken for each testcase in Rspec

I am using Rspec in my project where I would like to print the time taken by each testcase, Is there any way Rspec is providing any prebuilt function? I can take the starting time of the testcase by example.execution_result.started_at but I don't know how to take the end time of testcase, If I can take the end time, then I can subtract the end time from starting time to get the time duration for each testcase. Is there any one help me at this place? I have written this code

around(:each) do |example|  startTime=Time.now  var=example.run  puts var  endTime=Time.now  duration=endTime-startTime  puts "Time Taken->#{duration.to_f/60.to_f}"end

But I strongly believe Rspec must be giving some predefined method to return the duration of each testcase, do you anyone know that?
