It does ! The brain is able to calculate differences in time of two
equal frequency distributions, but only if they change in time. (The 
time resolution is 3*10E-5 seconds). If you START a sound left from your
head, the left ear will produce nerve signals milliseconds before the
right ear.
You can test it out : generate a constant sine tone with one of your
synths 
and seperate the original signal and one phase shifted signal for your
left
and right ear. You will hear a sine tone in the centre of your head !
But : (perhaps you try this one with the computer) The original sine
tone
amplitude modulated with a square wave for example, and with a little
phase
shift of the right-ear-signal will sound like if the signal comes from
your left (Not only the phase of the sine is shifted, but also attack
and 
instanteneous release of the signal !!)
(Sorry, i don't want to sound like a teacher)

No. It doesn't. As i said : what happens in the brain is very very very
comlex.
