When that happens next time, please show the exact value of the
relevant timer as a Lisp data structure.  (You should be able to find
it in the variable timer-list.)  Also, show the value returned by the
function current-time at that point.

In addition, please show the information collected by
"M-x report-emacs-bug RET", I don't think you included it with your
original report.

Thanks.
