Timecop.freeze(time) do |frozen_time|
  frozen_time == Time.local # => true
end

Timecop.travel

Timecop.travel(Time.local(2014, 1, 1, 0, 0, 0)) do
  Time.local # => "2014-01-01 00:00:00 +0900"
  sleep(5.seconds)
  Time.local # => "2014-01-01 00:00:05 +0900"

# seconds will now seem like hours
Timecop.scale(3600)

Time.local # => "2017-08-28 23:50:06 +0900"

sleep(2.seconds)
# 2 seconds later, hours have passed and it's gone from
