You can use NTP to synchronize the machines in a network. Then you use the local time i.e. System.currentTimeMillis() to get the time locally.

One way to make the timing easier is to send the time in the message. This way you can compare the time sent with the time received to get the latency.

Note: this is only accurate to milli-seconds. For greater accuracy you need special infrastructure.
