Instead of apply(f, args) you should write:

f(*args)

If you have keyword arguments as well (or instead):

f(*args, **kwargs)

Chris Rebert has already mentioned the sched module. Otherwise, put the 
function call in a thread, and have the thread use time.sleep to wait 
until the right time to execute.
