Zonebie plugin that prints details of the random timezone (if available)
gem "zonebie-info"
In spec_helper.rb:
require 'zonebie/info/rspec'
In env.rb
require 'zonebie/info/cucumber'
zonebie-info depends on Zonebie so all you have to do is replace calls to Zonebie.set_random_timezone with:
Zonebie.set_timezone_with_info
Then, after your tests have run, you need to call Zonebie.print_timezone_info in the after hook
Data is collected in a separate thread so shouldn't slow down your tests by too much.
