Expect the same here. I believe they are not guaranteed for accuracy... from Apple:

"Because of the various input sources a typical run loop manages, the effective resolution of the time interval for a timer is limited to on the order of 50-100 milliseconds."

Reference google for NSTimer class reference.

I'm wondering generally how accurate timers can be expected to be. Are they generally accurate within a few ms depending on what else is going on in an application? Is threading an answer to most accurate timing? Just curious
here. I'm coming from another language where timers can be off fairly
significantly depending on drawing activity.
