timer-set-time-with-usecs
timer-set-time-with-usecs is a compiled Lisp function in `timer.el
'.
(timer-set-time-with-usecs TIMER TIME USECS &optional DELTA)
This function is obsolete since 22.1;
use `timer-set-time' and `timer-inc-time' instead.
Set the trigger time of TIMER to TIME plus USECS.
TIME must be in the internal format returned by, e.g., `current-time'.
The microsecond count from TIME is ignored, and USECS is used instead.
If optional fourth argument DELTA is a positive number, make the timer
fire repeatedly that many seconds apart.
