How do I delete the timer generated by the tic function?

When connecting to an arduino, oftentimes a timer will interrupt any commands I might have. Therefore, I've been deleting timers from my code and the arduino works well.

However, one process I have uses tic, but toc still returns the number of seconds from tic, even when I implement delete(timerfindall). Any hard clear-all functions that can do this for me?

does not create any timers. tic does the equivalent of

function current_time = tic
  global tic_latest_time
  current_time = now();
  if nargout == 0
    tic_latest_time = current_time;
  end

and toc does the equivalent of

   function elapsed_time = toc(tic_time)
      global tic_latest_time;
      current_time = now();
      if nargin > 0
         elapsed_time = current_time - tic_time;
      else
         elapsed_time = current_time - tic_latest_time;
      end

except that a 64 bit integer timer is used instead of now(), and the resulting 64 bit difference is scaled into seconds.
