Yes. The only place I've deployed constantly-firing timer code is on a server that runs 24/7, and in a particular full-screen mode that the user only enters for a short time.

Personally, I'd probably just do a non-repeating timer, set to fire at the next second roll-over. Alloc'ing, scheduling and releasing 1 timer per second is not a lot of overhead.
