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 may be accurate enough for you. If you only require millisecond granularity, the above solution should be sufficient. It's just that if you want an order of magnitude better resolution, things get tricky very quickly.
