I have been using mach_absolute_time() for all my timing functions so far. calculating how long between frames ect.

I now want to get the exact time touch input events happen using event.timestamp in the touch callbacks.

the problem is these two seem to use completely different timers. sure, you can get them both in seconds, but their origins are different and seemingly random...

is there any way to sync the two different timers?

or is there anyway to get access to the same timer that the touch input uses to generate that timestamp property? otherwise its next to useless.
