I was thinking about how to implement a process that gives the number of discrete intervals in time that occurred since it started. Am I losing accuracy here? How do I implement this without loss of accuracy after a while and after heavy client abuse. I am kind of stumped how to do this in Erlang.

-module(clock).
-compile([export_all]).

start(Time) ->
    register(clock, spawn(fun() -> tick(Time, 0) end)).

stop() -> clock ! stop.

tick(Time, Count) ->
    receive
        nticks ->
            io:format("~p ticks have passed since start~n", [Count])
    after 0 -> true
    end,
    receive
        stop ->
            void
    after Time ->
            tick(Time, Count + 1)
    end.
