If you assume a client-server model, from the client's view there are 4 time stamps: when the request leaves the client when the request arrives at the server when the response leaves the server when the response arrives at the client If you assume tha the network delays are symmetric, you can figure out the network delay and clock offset from those 4 numbers. The key idea is that the server can twiddle it's thumbs and do lots of crypto stuff and/or whatever else it wants between the time the request arrives and the time it sends the response. That's why you need 4 time stamps rather than only 3. -- These are my opinions, not necessarily my employer's.
