Elixir version of this in case anyone wants it.

defp system_time do                                                                                                                                                                                   
  {mega, seconds, ms} = :os.timestamp()                                                                                                                                                               
  (mega*1000000 + seconds)*1000 + :erlang.round(ms/1000)                                                                                                                                              
end

If you are on Erlang 18 or newer, look into using :erlang.system_time instead of this.

Thanks @joakimk . :erlang.system_time / 1.0e6 |> round works to get the millis

there is Erlang function to get timestamp in ms :os.system_time(:millisecond)
