It seems a stupid response from ntpdate since I asked the time from the server. So, ntpdate maybe isn't what I should be using. There was a discussion about time services on this list some time ago and at that time I decided chrony should be used so I will try it next. I don't want a service that keeps banging on the server. Once a day seems reasonable to me. Can chrony be configured to check in once a day. I don't expect the time to be more accurate than 30 seconds. The computer does run 24/7 so the drift is in the software. Best regards, Fred
