you got it right the first time. its shutter lag
in case you got it mixed up with something else, shutter lag is the interval period between the moment you press the button till the shutter starts moving
there're actually a few timings. some depend on the lens used, i.e. autofocus, while others is the lag due to the camera.
Imaging resource did some test and got the following results for the D70.
Lens dependent:
Shutter lag, full autofocus (no flash) 0.342-0.486s with kit lens
Non-lens dependent:
Shutter lag, manual focus 0.155s
Shutter lag, prefocus 0.124s
Comparison with other cameras' timings (D100/300D):
Shutter lag, full autofocus (no flash) 0.15s with 24-85/0.25-0.278 with 18-55 kit
Shutter lag, manual focus 0.1/0.248s
Shutter lag, prefocus 0.1/0.142s
From the tests, D70 seems slower than the D100 in terms shutter lag. The D70's AF-S kit lens slows down the full autofocus shutter lag compared to the 300D's timing with non-USM kit lens, but the manual and prefocus lags are much faster.
