Hi David,

yes, it's too bad. I just arrieved at work 2 hours ago, turned on the machine, wich has an initial offset of 50 ms today (last was 5?!) and I sit here since two hours reading newpapers, waiting for time to settle in order to sync the next machine to it.. Well, I will look into chrony, that's for sure and I can report back if anyone is interrested..
