your signal is sampled with a sample rate. You can now estimate the
time shift in (fractional) samples, and calculate the "wall clock"
time difference by dividing by the sampling rate.
You, as a user, set the sampling rate that your device uses. The
B210 is very flexible in respect to that.

Thank you for your time,
I need to transmit a signal and then receive it, so I
need the time difference between the two signals. I thought that
I need a clock in both so I could compare in the same time scale
the two signals. Thats why I need the clock.
Or how can I take the time between the 2 signals?

Hi Marcus, I know that the clock of the USRP b210
is 62MHz, but I need to show it on the flowgraph to compare
the phase of two signals.
I'm really confused. You *can* configure the master clock rate,
which is the rate at which the signal is sampled, to be up to
61.44MHz, but that's neither the default nor 62MHz. There are
several clocks in the B210, so maybe I'm missing something.
Where does that freuquency come from? What does it signify?
Why do you need it to compare phases? Of what?
