Time synchronization between webcoket api server and own server

Hello. Tell me if there is a way to achieve time synchronization between the Api server, which subscribes to the Api via webcoket?
There is a request, ping-pong, which, on command, sends the time to my server and receives a response for some time (I assume the time of the server). And what can this give? You can simply measure the time from sending to receiving a request.
