I have just conducted a small experiment. During a set of five five-minute intervals The BIPM (Bureau International des Poids et Mesures) website's current-UTC value transmission from Sèvres (near Paris) to my workstation in Ashland (near Boston) had a mean transmission-delay of 0.11 sec and mi

Time Synchronization Latency

2006-04-05 Thread Curt Thompson
Hello, I have a general question regarding the time synchronization across heterogeneous servers that span thousands of miles apart from each other. I have a large sysplex and distributed server environment, utilizing an IP network. I have an NTP instance running on several of my MF servers, in wh
