How do you measure the phase difference between two different signals?

In pure Matlab, or with the Signal Processing Toolbox?
What exactly are the available inputs? Are the two signals time synchronized? Are they the same sampling frequency? The same duration?

then simply do like wiki suggests:
A sine (or cosine) equation looks like y=Asin(wx-t) [or y=Acos(wx-t)]. The phase shift is "t." ("A" is the amplitude and "w" is the frequency.)
Compute the shift for each one and subtract, for y=0
