I am interested in measuring the latency or the travel time of each tick from the Dukascopy servers to my server.

Using some modified code from viewtopic.php?f=65&t=43968&p=57154&hilit=ping#p57154 I can see that on average my server is -91ms different in time to the dukascopy server. I can see that the tick instant differences vary from -200 to +0 ms, however this does not tell me if each tick is taking 50ms to travel from the dukascopy server or if it is taking 1000ms.

To trade I really want to know that what I am seeing on my server is current, and I definitely do not want to be trading on data that is already a second old.

So my question is how do I accurately get the dukascopy server time or syncronise my time with the Dukacopy servers? Do you run a time server that I can syncronise my machine with? Do you have any suggestions on how I can view the complete latency?
