Hi Fabiana,
 
the only way to do that is if you know the time difference between the machines.
It´s not so easy however if you use windows you could try synchronizing both 
endpoints by using: 
w32tm /config /manualpeerlist:[IP to synchronize to] /update 
/syncfromflags:MANUAL
 
and then monitor the time difference with:
w32tm /stripchart /computer:[IP to synchronize to]
 
,you always can have a delay reference by pinging and dividing by 2 the RTT.

        so ... it is not reliable if i substract the time i hav in the client 
minus the time i have in the server to get my end the end delay?

                It is within the limits of ntp.  Unless there is a WAN 
involved, the
                packets are flying around at an order of magnitude faster than 
what ntp
                can provide (ms resolution)
