You can do

rsp = nil
t=time_method do
   rsp = Net::HTTP.get_response(URI.parse(url).host, URI.parse(url).path)
end

Since rsp was bound outside the scope of a block, it gets closed over, so
rebinding it will alter the outer variable (unlike Python's lambdas, or most
other languages for that matter)

You might consider using Ruby's built-in "benchmark" library as well:

require "benchmark"

rsp = nil
puts Benchmark.measure do
  rsp = Net::HTTP.get_response(URI.parse(url).host, URI.parse(url).path)
end
