Turns out eventual consistency doesn't work well with chat apps.

The eventual consistency part of skype doesn't really cause problems. But how it screws up simple timestamping is quite another question.

The timestamp probably isn't to the MS, and/or there may be some drift on whichever server recorded the incoming message... it should be set to ms on the client, and only in the case of > 2s drift be adjusted on the server.

Your comment made me laugh, but this issue is very sad. How can a chat app that constantly flips messages in transit could pass any QI, for whatever low bar we set?
