The timer goes off each second, and then calls various routines to see if they 
have any work to do.  Many of those routines decrement a counter each time they 
get called and then do the real work (such as send a request) when the counter 
reaches zero.

It would be possible to peek ahead and see when the next time any work will 
actually get done and set the timer that far ahead.

Most of the PI type work is in response to reply packets coming back.  The 
timer triggers sending the request that makes the reply.

These are my opinions.  I hate spam.
