See the entries timers [1] and idle timers [2] in the Emacs Lisp manual.

Basically, you call

  (run-at-time "12:00" my-function)

for calling my-function at an absolute time, or

  (run-at-time "1 min" my-function)

to call my-function a minute from now. Repeats can be specified, etc.

The "idle" variants are for when you want to specify that Emacs be idle
for that long to actually call your function.

See the docs for the gories. Or ask here for more specifics.
