NSTimeInterval someInterval = [NSDate timeIntervalSinceReferenceDate];
From the docs:
"NSTimeInterval is always specified in seconds; it yields sub-
millisecond precision over a range of 10,000 years."

Hello,
Not sure I should ask this here.
How do I get time measurements in milliseconds? What is the accuracy
of the mac's C library implementation ?
I am using the clock() function from time.h and measuring
differences in seconds between the trigering of a NSTimer.
The NSTimer fires every 0.1 secs, and in the event code I measure
the difference between the current clock() call and the previous. I
then divide it by the CLOCKS_PER_SEC constant and get two orders of
magnitude difference than the interval in the timer. I get 0.001
secs instead of the 0.1 of the NSTimer.
Any ideias ?
