You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: clocks.rb
    path of file: ./repos/jruby/spec/ruby/core/process/fixtures
    
    the code of the file until where you have to start completion: module ProcessSpecs
  def self.clock_constants
    clocks = []

    platform_is_not :windows, :solaris do
      clocks += Process.constants.select { |c| c.to_s.start_with?('CLOCK_') }

      # These require CAP_WAKE_ALARM and are not documented in
      # Process#clock_gettime. They return EINVAL if the permission
      # is not granted.
      clocks -= [:CLOCK_BOOTTIME_ALARM, :CLOCK_REAL
    
  def self.clock_constants
    clocks = []

    platform_is_not :windows, :solaris do
      clocks += Process.constants.select { |c| c.to_s.start_with?('CLOCK_') }

      # These require CAP_WAKE_ALARM and are not documented in
      # Process#clock_gettime. They return EINVAL if the permission
      # is not granted.
      clocks -= [:CLOCK_BOOTTIME_ALARM, :CLOCK_REALTIME_ALARM]
    end

    clocks.sort.map { |c|
      [c, Process.const_get(c)]
    }
  end
end
