      Calling `travel_to` with a block, when we have previously already made a call to `travel_to`, can lead to confusing time stubbing.

      Instead of:

         travel_to 2.days.from_now do
           # 2 days from today
           travel_to 3.days.from_now do
             # 5 days from today
           end
         end

      preferred way to achieve above is:

         travel 2.days do
           # 2 days from today
         end

         travel 5.days do
           # 5 days from today
         end

          MSG
          raise travel_to_nested_block_call
        end

        if date_or_time.is_a?(Date) && !date_or_time.is_a?(DateTime)
          now = date_or_time.midnight.to_time

        now = now.change(usec: 0) unless with_usec

        # +now+ must be in local system timezone, because +Time.at(now)+
