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: time_query.rb
    path of file: ./repos/influxer/lib/influxer/metrics/relation
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Influxer
  module TimeQuery #:nodoc:
    TIME_ALIASES = {
      hour: "1h",
      minute: "1m",
      se
    
    def past(val)
      case val
      when Symbol
        where("time > now() - #{TIME_ALIASES[val] || ("1" + val.to_s)}")
      when String
        where("time > now() - #{val}")
      else
        where("time > now() - #{val.to_i}s")
      end
